113-594: Terminologia Anatomica (commonly abbreviated TA) is the international standard for human anatomical terminology. It is developed by the Federative International Programme on Anatomical Terminology , a program of the International Federation of Associations of Anatomists (IFAA). The sixth edition of the previous standard, Nomina Anatomica , was released in 1989. The first edition of Terminologia Anatomica , superseding Nomina Anatomica,

226-401: A cultivated variety of Beta vulgaris in the family Amaranthaceae , the tuberous root of which contains a high proportion of sucrose. It is cultivated as a root crop in temperate regions with adequate rainfall and requires a fertile soil. The crop is harvested mechanically in the autumn and the crown of leaves and excess soil removed. The roots do not deteriorate rapidly and may be left in

339-519: A cell . Here, parts of DNA are copied and sent to the body of the cell via RNA . The RNA is then used to create proteins , which form the basis for cells, their activity, and their products. Proteins dictate cell function and gene expression, a cell is able to self-regulate by the amount of proteins produced. However, not all cells have DNA; some cells such as mature red blood cells lose their nucleus as they mature. The body consists of many different types of tissue , defined as cells that act with

452-483: A diet high in free sugar, especially refined sugar, was damaging to human health . In 2015, the World Health Organization strongly recommended that adults and children reduce their intake of free sugars to less than 10% of their total energy intake and encouraged a reduction to below 5%. In general, high sugar consumption damages human health more than it provides nutritional benefit and is associated with

565-576: A negligible amount of iron or any other nutrient. Because brown sugar contains 5–10% molasses reintroduced during processing, its value to some consumers is a richer flavor than white sugar. High sugar consumption damages human health more than it provides nutritional benefit, and in particular is associated with a risk of cardiometabolic health detriments. Sugar refiners and manufacturers of sugary foods and drinks have sought to influence medical research and public health recommendations, with substantial and largely clandestine spending documented from

678-420: A number of body cavities , separated areas which house different organ systems. The brain and central nervous system reside in an area protected from the rest of the body by the blood brain barrier . The lungs sit in the pleural cavity . The intestines , liver , and spleen sit in the abdominal cavity . Height, weight, shape and other body proportions vary individually and with age and sex. Body shape

791-399: A number of sexually transmitted infections including syphilis , HIV , chlamydia , HPV and genital warts . Cancer can affect most parts of the reproductive system including the penis , testicles , prostate , ovaries , cervix , vagina , fallopian , uterus and vulva . The respiratory system consists of the nose, nasopharynx , trachea , and lungs . It brings oxygen from

904-607: A panel at the 2022 International Federation of Associations of Anatomists Congress, one author stated "the Terminologia Anatomica generally receives no attention in medical terminology courses", but stressed its importance. The TA is not well established in other languages, such as French. The English equivalent names are often inconsistent if viewed as translations of the accompanying Latin phrases. The Terminologia Anatomica specifically excludes eponyms, as they were determined to "give absolutely no anatomical information about

1017-510: A risk of cardiometabolic and other health detriments. The etymology of sugar reflects the commodity's spread. From Sanskrit śarkarā , meaning "ground or candied sugar", came Persian shakar and Arabic sukkar . The Arabic word was borrowed in Medieval Latin as succarum , whence came the 12th century French sucre and the English sugar . Sugar was introduced into Europe by

1130-505: A specialised function. The study of tissues is called histology and is often done with a microscope . The body consists of four main types of tissues. These are lining cells ( epithelia ), connective tissue , nerve tissue and muscle tissue . Cells that line surfaces exposed to the outside world or gastrointestinal tract ( epithelia ) or internal cavities ( endothelium ) come in numerous shapes and forms – from single layers of flat cells , to cells with small beating hair-like cilia in

1243-451: A sweet taste but are not classified as sugar. Sugars are found in the tissues of most plants. Honey and fruits are abundant natural sources of simple sugars. Sucrose is especially concentrated in sugarcane and sugar beet , making them ideal for efficient commercial extraction to make refined sugar. In 2016, the combined world production of those two crops was about two billion tonnes . Maltose may be produced by malting grain. Lactose

1356-440: A very limited extent, though ruminants can do so with the help of symbiotic bacteria in their gut. DNA and RNA are built up of the monosaccharides deoxyribose and ribose , respectively. Deoxyribose has the formula C 5 H 10 O 4 and ribose the formula C 5 H 10 O 5 . Because sugars burn easily when exposed to flame, the handling of sugars risks dust explosion . The risk of explosion

1469-415: A whiter product. About 2,500 litres (660 US gal) of irrigation water is needed for every one kilogram (2.2 pounds) of sugar produced. In 2020, global production of sugar beets was 253 million tonnes , led by Russia with 13% of the world total (table). Sugar beet became a major source of sugar in the 19th century when methods for extracting the sugar became available. It is a biennial plant ,

1582-442: Is swallowed , and moves through the esophagus to the stomach . In the stomach, food is mixed with gastric acids to allow the extraction of nutrients . What is left is called chyme ; this then moves into the small intestine , which absorbs the nutrients and water from the chyme. What remains passes on to the large intestine , where it is dried to form feces ; these are then stored in the rectum until they are expelled through

1695-433: Is a common disease in which one or more stones form in the gallbladder or biliary tract . Most people are asymptomatic but if a stone blocks the biliary tract, it causes a gallbladder attack , symptoms may include sudden pain in the upper right abdomen or center of the abdomen. Nausea and vomiting may also occur. Typical treatment is removal of the gallbladder through a procedure called a cholecystectomy . Having gallstones

1808-421: Is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars. Longer chains of monosaccharides (>2) are not regarded as sugars and are called oligosaccharides or polysaccharides . Starch is a glucose polymer found in plants, the most abundant source of energy in human food . Some other chemical substances, such as ethylene glycol , glycerol and sugar alcohols , may have

1921-444: Is a risk factor for gallbladder cancer , which although quite uncommon, is rapidly fatal if not diagnosed early. The circulatory system consists of the heart and blood vessels ( arteries , veins and capillaries ). The heart propels the circulation of the blood, which serves as a "transportation system" to transfer oxygen , fuel, nutrients, waste products, immune cells and signaling molecules (i.e. hormones ) from one part of

2034-474: Is any of several species, or their hybrids, of giant grasses in the genus Saccharum in the family Poaceae . They have been cultivated in tropical climates in the Indian subcontinent and Southeast Asia over centuries for the sucrose found in their stems. Sugar cane requires a frost-free climate with sufficient rainfall during the growing season to make full use of the plant's substantial growth potential. The crop

2147-415: Is brought by the ureters from the kidneys down to the bladder . The smooth muscle lining the ureter walls continuously tighten and relax through a process called peristalsis to force urine away from the kidneys and down into the bladder. Small amounts of urine are released into the bladder every 10–15 seconds. The bladder is a hollow balloon shaped organ located in the pelvis . It stores urine until

2260-484: Is due to the amount of molasses they contain. They may be classified based on their darkness or country of origin. Worldwide sugar provides 10% of the daily calories (based on a 2000 kcal diet). In 1750, the average Briton got 72 calories a day from sugar. In 1913, this had risen to 395. In 2015, sugar still provided around 14% of the calories in British diets. According to one source, per capita consumption of sugar in 2016

2373-437: Is filtered out, many of the impurities are removed at the same time. Removal of color is achieved by using either a granular activated carbon or an ion-exchange resin . The sugar syrup is concentrated by boiling and then cooled and seeded with sugar crystals, causing the sugar to crystallize out. The liquor is spun off in a centrifuge and the white crystals are dried in hot air and ready to be packaged or used. The surplus liquor

2486-444: Is harvested mechanically or by hand, chopped into lengths and conveyed rapidly to the processing plant (commonly known as a sugar mill ) where it is either milled and the juice extracted with water or extracted by diffusion. The juice is clarified with lime and heated to destroy enzymes . The resulting thin syrup is concentrated in a series of evaporators, after which further water is removed. The resulting supersaturated solution

2599-418: Is higher when the sugar has been milled to superfine texture, such as for use in chewing gum . The 2008 Georgia sugar refinery explosion , which killed 14 people and injured 36, and destroyed most of the refinery, was caused by the ignition of sugar dust. In its culinary use, exposing sugar to heat causes caramelization . As the process occurs, volatile chemicals such as diacetyl are released, producing

2712-419: Is influenced by the distribution of bones, muscle and fat tissue . Human physiology is the study of how the human body functions. This includes the mechanical, physical, bioelectrical , and biochemical functions of humans in good health, from organs to the cells of which they are composed. The human body consists of many interacting systems of organs. These interact to maintain homeostasis , keeping

2825-399: Is known as affination and involves immersing the sugar crystals in a concentrated syrup that softens and removes the sticky brown coating without dissolving them. The crystals are then separated from the liquor and dissolved in water. The resulting syrup is treated either by a carbonatation or by a phosphatation process. Both involve the precipitation of a fine solid in the syrup and when this

2938-429: Is made from raw sugar that has undergone a refining process to remove the molasses . Raw sugar is sucrose which is extracted from sugarcane or sugar beet . While raw sugar can be consumed, the refining process removes unwanted tastes and results in refined sugar or white sugar. The sugar may be transported in bulk to the country where it will be used and the refining process often takes place there. The first stage

3051-454: Is made into refiners' molasses. The International Commission for Uniform Methods of Sugar Analysis sets standards for the measurement of the purity of refined sugar, known as ICUMSA numbers; lower numbers indicate a higher level of purity in the refined sugar. Refined sugar is widely used for industrial needs for higher quality. Refined sugar is purer (ICUMSA below 300) than raw sugar (ICUMSA over 1,500). The level of purity associated with

3164-509: Is mostly responsible for gathering information with sensory neurons and directing body movements with motor neurons . From a functional perspective, the nervous system is again typically divided into two component parts: the somatic nervous system (SNS) and the autonomic nervous system (ANS). The SNS is involved in voluntary functions like speaking and sensory processes . The ANS is involved in involuntary processes, such as digestion and regulating blood pressure . The nervous system

3277-414: Is seeded with sugar crystals, facilitating crystal formation and drying. Molasses is a by-product of the process and the fiber from the stems, known as bagasse , is burned to provide energy for the sugar extraction process. The crystals of raw sugar have a sticky brown coating and either can be used as they are, can be bleached by sulfur dioxide , or can be treated in a carbonatation process to produce

3390-405: Is similar to the circulatory system in terms of both its structure and its most basic function, to carry a body fluid. The musculoskeletal system consists of the human skeleton (which includes bones , ligaments , tendons , joints and cartilage ) and attached muscles . It gives the body basic structure and the ability for movement. In addition to their structural role, the larger bones in

3503-420: Is sometimes used as a sweetener for foods (e.g., toast and cereal) and beverages (e.g., coffee and tea). The average person consumes about 24 kilograms (53 pounds) of sugar each year. North and South Americans consume up to 50 kg (110 lb), and Africans consume under 20 kg (44 lb). As free sugar consumption grew in the latter part of the 20th century, researchers began to examine whether

3616-520: Is still used locally to make desserts today. Sugarcane is native of tropical areas such as the Indian subcontinent (South Asia) and Southeast Asia. Different species seem to have originated from different locations; Saccharum barberi originated in India, and S. edule and S. officinarum came from New Guinea . One of the earliest historical references to sugarcane is in Chinese manuscripts dating to

3729-430: Is subject to many different diseases. In epilepsy , abnormal electrical activity in the brain can cause seizures . In multiple sclerosis , the immune system attacks the nerve linings , damaging the nerves' ability to transmit signals. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig 's disease, is a motor neuron disease which gradually reduces movement in patients. There are also many other diseases of

3842-439: Is the only sugar that cannot be extracted from plants. It can only be found in milk, including human breast milk, and in some dairy products . A cheap source of sugar is corn syrup , industrially produced by converting corn starch into sugars, such as maltose, fructose and glucose. Sucrose is used in prepared foods (e.g., cookies and cakes), is sometimes added to commercially available ultra-processed food and beverages, and

3955-425: Is the organ of thought , emotion, memory , and sensory processing ; it serves many aspects of communication and controls various systems and functions. The special senses consist of vision , hearing , taste , and smell . The eyes , ears , tongue , and nose gather information about the body's environment. From a structural perspective, the nervous system is typically subdivided into two component parts:

4068-442: Is the study of the shape and form of the human body. The human body has four limbs (two arms and two legs), a head and a neck , which connect to the torso . The body's shape is determined by a strong skeleton made of bone and cartilage , surrounded by fat ( adipose tissue ), muscle, connective tissue , organs, and other structures. The spine at the back of the skeleton contains the flexible vertebral column , which surrounds

4181-433: Is variable in shape and size. It stores bile before it is released into the small intestine via the common bile duct to help with digestion of fats . It receives bile from the liver via the cystic duct , which connects to the common hepatic duct to form the common bile duct . The gallbladder gets its blood supply from the cystic artery , which in most people, emerges from the right hepatic artery . Gallstones

4294-590: The Khyber Pass and caravan routes. It was not plentiful or cheap in early times, and in most parts of the world, honey was more often used for sweetening. Originally, people chewed raw sugarcane to extract its sweetness. Even after refined sugarcane became more widely available during the European colonial era, palm sugar was preferred in Java and other sugar producing parts of southeast Asia, and along with coconut sugar ,

4407-441: The anus . The endocrine system consists of the principal endocrine glands : the pituitary , thyroid , adrenals , pancreas , parathyroids , and gonads , but nearly all organs and tissues produce specific endocrine hormones as well. The endocrine hormones serve as signals from one body system to another regarding an enormous array of conditions, resulting in variety of changes of function. The immune system consists of

4520-517: The central nervous system (CNS), composed of the brain and the spinal cord ; and the peripheral nervous system (PNS), composed of the nerves and ganglia outside the brain and spinal cord. The CNS is mostly responsible for organizing motion , processing sensory information , thought, memory, cognition and other such functions. It remains a matter of some debate whether the CNS directly gives rise to consciousness . The peripheral nervous system (PNS)

4633-468: The heart , lungs and liver . Many organs reside within cavities within the body. These cavities include the abdomen (which contains the stomach, for example) and pleura , which contains the lungs. The heart is an organ located in the thoracic cavity between the lungs and slightly to the left. It is surrounded by the pericardium , which holds it in place in the mediastinum and serves to protect it from blunt trauma, infection and help lubricate

4746-441: The kidneys filter the blood through their respective nephrons , removing waste products like urea , creatinine and maintaining the proper balance of electrolytes and turning the waste products into urine by combining them with water from the blood. The kidneys filter about 150 quarts (170 liters) of blood daily, but most of it is returned to the blood stream with only 1-2 quarts (1-2 liters) ending up as urine. The urine

4859-516: The molecular formula C 6 H 12 O 6 . The names of typical sugars end with - ose , as in "glucose" and " fructose ". Sometimes such words may also refer to any types of carbohydrates soluble in water. The acyclic mono- and disaccharides contain either aldehyde groups or ketone groups. These carbon-oxygen double bonds (C=O) are the reactive centers. All saccharides with more than one ring in their structure result from two or more monosaccharides joined by glycosidic bonds with

4972-456: The ovary of a female is penetrated by sperm . The egg then lodges in the uterus , where an embryo and later fetus develop until birth . Growth and development occur after birth, and include both physical and psychological development, influenced by genetic, hormonal, environmental and other factors. Development and growth continue throughout life, through childhood , adolescence , and through adulthood to old age , and are referred to as

5085-407: The sinoatrial node traveling through the atria causing them to pump blood into the ventricles . It then travels to the atrioventricular node , which makes the signal slow down slightly allowing the ventricles to fill with blood before pumping it out and starting the cycle over again. Coronary artery disease is the leading cause of death worldwide , making up 16% of all deaths. It is caused by

5198-400: The spinal cord , which is a collection of nerve fibres connecting the brain to the rest of the body. Nerves connect the spinal cord and brain to the rest of the body. All major bones, muscles, and nerves in the body are named, with the exception of anatomical variations such as sesamoid bones and accessory muscles . Blood vessels carry blood throughout the body, which moves because of

5311-421: The spleen and bone marrow . The digestive system consists of the mouth including the tongue and teeth , esophagus , stomach , ( gastrointestinal tract , small and large intestines , and rectum ), as well as the liver , pancreas , gallbladder , and salivary glands . It converts food into small, nutritional, non-toxic molecules for distribution and absorption into the body. These molecules take

5424-432: The testicles . The testicle is the gonad , the sex gland that produces the sperm cells . Unlike the egg cells in the female, sperm cells are produced throughout life. Other internal sex organs are the epididymides , vasa deferentia , and some accessory glands . Diseases that affect the reproductive system include polycystic ovary syndrome , a number of disorders of the testicles including testicular torsion , and

5537-420: The thorax and abdomen ), genitals , arms , hands , legs , and feet . The internal human body includes organs, teeth , bones , muscle , tendons , ligaments , blood vessels and blood , lymphatic vessels and lymph . The study of the human body includes anatomy , physiology , histology and embryology . The body varies anatomically in known ways. Physiology focuses on the systems and organs of

5650-427: The uterus , and the cervix . At birth there are about 70,000 immature egg cells that degenerate until at puberty there are around 40,000. No more egg cells are produced. Hormones stimulate the beginning of menstruation, and the ongoing menstrual cycles . The female external sex organs are the vulva ( labia , clitoris , and vestibule ). The male external genitalia include the penis and scrotum that contains

5763-441: The white blood cells , the thymus , lymph nodes and lymph channels, which are also part of the lymphatic system . The immune system provides a mechanism for the body to distinguish its own cells and tissues from outside cells and substances and to neutralize or destroy the latter by using specialized proteins such as antibodies , cytokines , and toll-like receptors , among many others. The integumentary system consists of

5876-449: The 12th century, the Republic of Venice acquired some villages near Tyre and set up estates to produce sugar for export to Europe. It supplemented the use of honey, which had previously been the only available sweetener. Crusade chronicler William of Tyre , writing in the late 12th century, described sugar as "very necessary for the use and health of mankind". In the 15th century, Venice

5989-557: The 1960s to 2016. The results of research on the health effects of sugary food and drink differ significantly, depending on whether the researcher has financial ties to the food and drink industry. A 2013 medical review concluded that "unhealthy commodity industries should have no role in the formation of national or international NCD [ non-communicable disease ] policy". Similar efforts to steer coverage of sugar-related health information have been made in popular media, including news media and social media. A 2003 technical report by

6102-675: The 8th century BCE, which state that the use of sugarcane originated in India. In the tradition of Indian medicine ( āyurveda ), sugarcane is known by the name Ikṣu , and sugarcane juice is known as Phāṇita . Its varieties, synonyms and characteristics are defined in nighaṇṭus such as the Bhāvaprakāśa (1.6.23, group of sugarcanes). Sugar remained relatively unimportant until the Indians discovered methods of turning sugarcane juice into granulated crystals that were easier to store and transport. The Greek physician Pedanius Dioscorides attested to

6215-656: The Arabs in Sicily and Spain. The English word jaggery , a coarse brown sugar made from date palm sap or sugarcane juice, has a similar etymological origin: Portuguese jágara from the Malayalam cakkarā , which is from the Sanskrit śarkarā . Sugar has been produced in the Indian subcontinent for thousands of years. Sugarcane cultivation spread from there into China via

6328-602: The Elder also described sugar in his 1st century CE Natural History : " Sugar is made in Arabia as well, but Indian sugar is better. It is a kind of honey found in cane, white as gum, and it crunches between the teeth. It comes in lumps the size of a hazelnut. Sugar is used only for medical purposes. " Crusaders brought sugar back to Europe after their campaigns in the Holy Land , where they encountered caravans carrying "sweet salt". Early in

6441-636: The IFAA General Assembly in 2020. The latest errata is dated August 2021. It contains a total of 7112 numbered terms (1-7113 skipping 2590), with some terms repeated. A 2014 survey of the American Association of Clinical Anatomists found that the TA preferred term had the highest frequency of usage in only 53% of the 25 anatomical terms surveyed, and was highest or second-highest for 92% of terms. 75% of respondents were unfamiliar with FIPAT and TA. In

6554-436: The ages of 9 and 13 and is characterized by ovulation and menstruation ; the growth of secondary sex characteristics, such as growth of pubic and underarm hair , breast , uterine and vaginal growth, widening hips and increased height and weight, also occur during puberty. Male puberty sees the further development of the penis and testicles . The female inner sex organs are the two ovaries, their fallopian tubes ,

6667-435: The air and excretes carbon dioxide and water back into the air. First, air is pulled through the trachea into the lungs by the diaphragm pushing down, which creates a vacuum . Air is briefly stored inside small sacs known as alveoli (sing.: alveolus) before being expelled from the lungs when the diaphragm contracts again. Each alveolus is surrounded by capillaries carrying deoxygenated blood, which absorbs oxygen out of

6780-420: The air and into the bloodstream . For the respiratory system to function properly, there need to be as few impediments as possible to the movement of air within the lungs. Inflammation of the lungs and excess mucus are common sources of breathing difficulties. In asthma , the respiratory system is persistently inflamed, causing wheezing or shortness of breath . Pneumonia occurs through infection of

6893-400: The alveoli, and may be caused by tuberculosis . Emphysema , commonly a result of smoking , is caused by damage to connections between the alveoli. The urinary system consists of the two kidneys , two ureters , bladder , and urethra . It removes waste materials from the blood through urine, which carries a variety of waste molecules and excess ions and water out of the body. First,

7006-406: The beating of the heart . Venules and veins collect blood low in oxygen from tissues throughout the body. These collect in progressively larger veins until they reach the body's two largest veins, the superior and inferior vena cava , which drain blood into the right side of the heart. From here, the blood is pumped into the lungs where it receives oxygen and drains back into the left side of

7119-467: The best and most complete account we have of a late medieval banquet" includes the first mention of sugar sculptures, as the final food brought in was "a heraldic menagerie sculpted in sugar: lions, stags, monkeys ... each holding in paw or beak the arms of the Hungarian king ". Other recorded grand feasts in the decades following included similar pieces. Originally the sculptures seem to have been eaten in

7232-427: The body contain bone marrow , the site of production of blood cells. Also, all bones are major storage sites for calcium and phosphate . This system can be split up into the muscular system and the skeletal system . The nervous system consists of the body's neurons and glial cells, which together form the nerves , ganglia and gray matter , which in turn form the brain and related structures. The brain

7345-423: The body in a stable state with safe levels of substances such as sugar and oxygen in the blood. Each system contributes to homeostasis, of itself, other systems, and the entire body. Some combined systems are referred to by joint names. For example, the nervous system and the endocrine system operate together as the neuroendocrine system . The nervous system receives information from the body, and transmits this to

7458-441: The body to another. Paths of blood circulation within the human body can be divided into two circuits: the pulmonary circuit , which pumps blood to the lungs to receive oxygen and leave carbon dioxide , and the systemic circuit, which carries blood from the heart off to the rest of the body. The blood consists of fluid that carries cells in the circulation, including some that move from tissue to blood vessels and back, as well as

7571-558: The body. The adult male body is about 60% total body water content of some 42 litres (9.2 imp gal; 11 US gal). This is made up of about 19 litres (4.2 imp gal; 5.0 US gal) of extracellular fluid including about 3.2 litres (0.70 imp gal; 0.85 US gal) of blood plasma and about 8.4 litres (1.8 imp gal; 2.2 US gal) of interstitial fluid , and about 23 litres (5.1 imp gal; 6.1 US gal) of fluid inside cells. The content, acidity and composition of

7684-412: The brain signals it to relax the urinary sphincter and release the urine into the urethra starting urination . A normal bladder can hold up to 16 ounces (half a liter) for 3–5 hours comfortably. Numerous diseases affect the urinary system including kidney stones , which are formed when materials in the urine concentrate enough to form a solid mass, urinary tract infections , which are infections of

7797-463: The brain via nerve impulses and neurotransmitters . At the same time, the endocrine system releases hormones, such as to help regulate blood pressure and volume. Together, these systems regulate the internal environment of the body, maintaining blood flow, posture, energy supply, temperature, and acid balance ( pH ). Development of the human body is the process of growth to maturity. The process begins with fertilisation, where an egg released from

7910-481: The buildup of plaque in the coronary arteries supplying the heart, eventually the arteries may become so narrow that not enough blood is able to reach the myocardium , a condition known as myocardial infarction or heart attack , this can cause heart failure or cardiac arrest and eventually death. Risk factors for coronary artery disease include obesity , smoking , high cholesterol , high blood pressure , lack of exercise and diabetes . Cancer can affect

8023-412: The cell numbers of all the organs of the body and cell types . The skin of the body is also host to billions of commensal organisms as well as immune cells. Not all parts of the body are made from cells. Cells sit in an extracellular matrix that consists of proteins such as collagen , surrounded by extracellular fluids. Cells in the body function because of DNA . DNA sits within the nucleus of

8136-452: The centers of distribution, became known for candied fruit, while Venice specialized in pastries, sweets (candies), and sugar sculptures . Sugar was considered to have "valuable medicinal properties" as a "warm" food under prevailing categories, being "helpful to the stomach, to cure cold diseases, and sooth lung complaints". A feast given in Tours in 1457 by Gaston de Foix , which is "probably

8249-479: The characteristic caramel flavor. Fructose, galactose, and glucose are all simple sugars, monosaccharides, with the general formula C 6 H 12 O 6 . They have five hydroxyl groups (−OH) and a carbonyl group (C=O) and are cyclic when dissolved in water. They each exist as several isomers with dextro- and laevo-rotatory forms that cause polarized light to diverge to the right or the left. Lactose, maltose, and sucrose are all compound sugars, disaccharides, with

8362-437: The colonization of tropical islands and areas where labor-intensive sugarcane plantations and sugar manufacturing facilities could be successful. World consumption increased more than 100 times from 1850 to 2000, led by Britain, where it increased from about 2 pounds per head per year in 1650 to 90 pounds by the early 20th century. In the late 18th century Britain consumed about half the sugar which reached Europe. After slavery

8475-409: The colors of sugar, expressed by standard number ICUMSA , the smaller ICUMSA numbers indicate the higher purity of sugar. Brown sugars are granulated sugars, either containing residual molasses, or with the grains deliberately coated with molasses to produce a light- or dark-colored sugar such as muscovado and turbinado . They are used in baked goods, confectionery, and toffees . Their darkness

8588-432: The covering of the body (the skin ), including hair and nails as well as other functionally important structures such as the sweat glands and sebaceous glands . The skin provides containment, structure, and protection for other organs, and serves as a major sensory interface with the outside world. The lymphatic system extracts, transports and metabolizes lymph, the fluid found in between cells. The lymphatic system

8701-444: The development and use of various artificial sweeteners . Scientifically, sugar loosely refers to a number of carbohydrates , such as monosaccharides , disaccharides , or oligosaccharides . Monosaccharides are also called "simple sugars", the most important being glucose. Most monosaccharides have a formula that conforms to C n H 2n O n with n between 3 and 7 ( deoxyribose being an exception). Glucose has

8814-623: The difficulty of importing sugar when shipping was subject to blockade . By 1880 the sugar beet was the main source of sugar in Europe. It was also cultivated in Lincolnshire and other parts of England, although the United Kingdom continued to import the main part of its sugar from its colonies. Until the late nineteenth century, sugar was purchased in loaves , which had to be cut using implements called sugar nips . In later years, granulated sugar

8927-459: The field for some weeks before being transported to the processing plant where the crop is washed and sliced, and the sugar extracted by diffusion. Milk of lime is added to the raw juice with calcium carbonate . After water is evaporated by boiling the syrup under a vacuum, the syrup is cooled and seeded with sugar crystals. The white sugar that crystallizes can be separated in a centrifuge and dried, requiring no further refining. Refined sugar

9040-458: The form of proteins (which are broken down into amino acids ), fats , vitamins and minerals (the last of which are mainly ionic rather than molecular). After being swallowed , food moves through the gastrointestinal tract by means of peristalsis : the systematic expansion and contraction of muscles to push food from one area to the next. Digestion begins in the mouth , which chews food into smaller pieces for easier digestion. Then it

9153-463: The form of storage polysaccharides such as starch or inulin . Starch, consisting of two different polymers of glucose, is a readily degradable form of chemical energy stored by cells , and can be converted to other types of energy. Another polymer of glucose is cellulose, which is a linear chain composed of several hundred or thousand glucose units. It is used by plants as a structural component in their cell walls. Humans can digest cellulose only to

9266-550: The general formula C 12 H 22 O 11 . They are formed by the combination of two monosaccharide molecules with the exclusion of a molecule of water. The sugar contents of common fruits and vegetables are presented in Table 1. Due to rising demand, sugar production in general increased some 14% over the period 2009 to 2018. The largest importers were China, Indonesia , and the United States. In 2022/3 world production of sugar

9379-403: The heart , though it is exceedingly rare and has usually metastasized from another part of the body such as the lungs or breasts . This is because the heart cells quickly stop dividing and all growth occurs through size increase rather than cell division . The gallbladder is a hollow pear-shaped organ located posterior to the inferior middle part of the right lobe of the liver . It

9492-434: The heart. From here, it is pumped into the body's largest artery , the aorta , and then progressively smaller arteries and arterioles until it reaches tissue. Here, blood passes from small arteries into capillaries , then small veins and the process begins again. Blood carries oxygen , waste products, and hormones from one place in the body to another. Blood is filtered at the kidneys and liver . The body consists of

9605-499: The human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis , with safe levels of substances such as sugar , iron , and oxygen in the blood. The body is studied by health professionals , physiologists, anatomists, and artists to assist them in their work. The human body is composed of elements including hydrogen , oxygen , carbon , calcium and phosphorus . These elements reside in trillions of cells and non-cellular components of

9718-421: The lungs, to column-like cells that line the stomach . Endothelial cells are cells that line internal cavities including blood vessels and glands. Lining cells regulate what can and cannot pass through them, protect internal structures, and function as sensory surfaces. Organs , structured collections of cells with a specific function, mostly sit within the body, with the exception of skin . Examples include

9831-504: The meal, but later they become merely table decorations, the most elaborate called trionfi . Several significant sculptors are known to have produced them; in some cases their preliminary drawings survive. Early ones were in brown sugar, partly cast in molds, with the final touches carved. They continued to be used until at least the Coronation Banquet for Edward VII of the United Kingdom in 1903; among other sculptures every guest

9944-403: The method in his 1st century CE medical treatise De Materia Medica : There is a kind of coalesced honey called sakcharon [i.e. sugar] found in reeds in India and Eudaimon Arabia similar in consistency to salt and brittle enough to be broken between the teeth like salt, In the local Indian language, these crystals were called khanda ( Devanagari : खण्ड, Khaṇḍa ), which is the source of

10057-526: The molecules in the open-chain form. Biopolymers of sugars are common in nature. Through photosynthesis, plants produce glyceraldehyde-3-phosphate (G3P), a phosphated 3-carbon sugar that is used by the cell to make monosaccharides such as glucose ( C 6 H 12 O 6 ) or (as in cane and beet) sucrose ( C 12 H 22 O 11 ). Monosaccharides may be further converted into structural polysaccharides such as cellulose and pectin for cell wall construction or into energy reserves in

10170-415: The movement of the heart via pericardial fluid . The heart works by pumping blood around the body allowing oxygen , nutrients , waste , hormones and white blood cells to be transported. The heart is composed of two atria and two ventricles . The primary purpose of the atria is to allow uninterrupted venous blood flow to the heart during ventricular systole . This allows enough blood to get into

10283-511: The named structure, and vary considerably between countries and cultures". In a 2023 study of eight gynecologic eponyms, the TA term was preferred in two cases, and showed a significant trend towards TA adoption in three others, leaving three non-TA terms likely to remain in common use. Terminologia Anatomica is divided into 16 chapters grouped into five parts. The official terms are in Latin. Although equivalent English-language terms are provided, only

10396-407: The nervous system. The purpose of the reproductive system is to reproduce and nurture the growth of offspring. The functions include the production of germ cells and hormones. The sex organs of the male reproductive system and the female reproductive system develops and mature at puberty . These systems include the internal and external genitalia . Female puberty generally occurs between

10509-498: The north coast of Brazil, Demarara , and Surinam . It took until 1600 for Brazilian sugar production to exceed that of São Tomé , which was the main center of sugar production in sixteenth century. Sugar was a luxury in Europe until the early 19th century, when it became more widely available, due to the rise of beet sugar in Prussia , and later in France under Napoleon . Beet sugar

10622-431: The official Latin terms are used as the basis for creating lists of equivalent terms in other languages. TA1998: TA2: Human anatomy The human body is the entire structure of a human being . It is composed of many different types of cells that together create tissues and subsequently organs and then organ systems . The external human body consists of a head , hair , neck , torso (which includes

10735-402: The principal monosaccharides present in the blood and internal tissues include glucose, fructose, and galactose. Many pentoses and hexoses can form ring structures . In these closed-chain forms, the aldehyde or ketone group remains non-free, so many of the reactions typical of these groups cannot occur. Glucose in solution exists mostly in the ring form at equilibrium , with less than 0.1% of

10848-498: The process of aging . Sugar Sugar is the generic name for sweet-tasting , soluble carbohydrates , many of which are used in food. Simple sugars, also called monosaccharides , include glucose , fructose , and galactose . Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar

10961-407: The resultant loss of a molecule of water ( H 2 O ) per bond. Monosaccharides in a closed-chain form can form glycosidic bonds with other monosaccharides, creating disaccharides (such as sucrose ) and polysaccharides (such as starch or cellulose ). Enzymes must hydrolyze or otherwise break these glycosidic bonds before such compounds become metabolized . After digestion and absorption

11074-554: The seventh century. Chinese documents confirm at least two missions to India, initiated in 647 CE, to obtain technology for sugar refining. Nearchus , admiral of Alexander the Great , knew of sugar during the year 325 BC because of his participation in the campaign of India led by Alexander ( Arrian , Anabasis ). In addition to the Greek physician Pedanius Dioscorides , the Roman Pliny

11187-405: The urinary tract and can cause pain when urinating, frequent urination and even death if left untreated. Renal failure occurs when the kidneys fail to adequately filter waste from the blood and can lead to death if not treated with dialysis or kidney transplantation . Cancer can affect the bladder , kidneys , urethra and ureters , with the latter two being far more rare. Human anatomy

11300-417: The ventricles during atrial systole . Consequently, the atria allows a cardiac output roughly 75% greater than would be possible without them. The purpose of the ventricles is to pump blood to the lungs through the right ventricle and to the rest of the body through the left ventricle. The heart has an electrical conduction system to control the contraction and relaxation of the muscles. It starts in

11413-401: The water inside and outside cells is carefully maintained. The main electrolytes in body water outside cells are sodium and chloride , whereas within cells it is potassium and other phosphates . The body contains trillions of cells , the fundamental unit of life. At maturity, there are roughly 30 trillion cells, and 38 trillion bacteria in the body, an estimate arrived at by totaling

11526-608: The word candy . Indian sailors, who carried clarified butter and sugar as supplies, introduced knowledge of sugar along the various trade routes they travelled. Traveling Buddhist monks took sugar crystallization methods to China. During the reign of Harsha (r. 606–647) in North India , Indian envoys in Tang China taught methods of cultivating sugarcane after Emperor Taizong of Tang (r. 626–649) made known his interest in sugar. China established its first sugarcane plantations in

11639-581: Was abolished , the demand for workers in European colonies in the Caribbean was filled by indentured laborers from the Indian subcontinent . Millions of enslaved or indentured laborers were brought to various European colonies in the Americas, Africa and Asia (as a result of demand in Europe for among other commodities, sugar), influencing the ethnic mixture of numerous nations around the globe. Sugar also led to some industrialization of areas where sugar cane

11752-429: Was 186 Mt, and in 2023/4 an estimated 194 Mt - a surplus of 5 Mt, according to Ragus . Sugar cane accounted for around 21% of the global crop production over the 2000–2021 period. The Americas was the leading region in the production of sugar cane (52% of the world total). Global production of sugarcane in 2020 was 1.9 billion tonnes, with Brazil producing 40% of the world total and India 20% (table). Sugarcane

11865-478: Was a German invention, since, in 1747, Andreas Sigismund Marggraf announced the discovery of sugar in beets and devised a method using alcohol to extract it. Marggraf's student, Franz Karl Achard , devised an economical industrial method to extract the sugar in its pure form in the late 18th century. Achard first produced beet sugar in 1783 in Kaulsdorf , and in 1801, the world's first beet sugar production facility

11978-517: Was another early manufacturer of sugar cubes at his refineries in Liverpool and London. Tate purchased a patent for sugar-cube manufacture from German Eugen Langen , who in 1872 had invented a different method of processing of sugar cubes. Sugar was rationed during World War I , though it was said that "No previous war in history has been fought so largely on sugar and so little on alcohol", and more sharply during World War II . Rationing led to

12091-517: Was developed by the Federative Committee on Anatomical Terminology (FCAT) and the International Federation of Associations of Anatomists (IFAA) and released in 1998. In April 2011, this edition was published online by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT. The first edition contained 7635 Latin items. The second edition was released online by FIPAT in 2019 and approved and adopted by

12204-595: Was established in Cunern , Silesia (then part of Prussia, now Poland ). The works of Marggraf and Achard were the starting point for the sugar industry in Europe, and for the modern sugar industry in general, since sugar was no longer a luxury product and a product almost only produced in warmer climates. Sugar became highly popular and by the 19th century, was found in every household. This evolution of taste and demand for sugar as an essential food ingredient resulted in major economic and social changes. Demand drove, in part,

12317-809: Was given a sugar crown to take away. In August 1492, Christopher Columbus collected sugar cane samples in La Gomera in the Canary Islands , and introduced it to the New World . The cuttings were planted and the first sugar-cane harvest in Hispaniola took place in 1501. Many sugar mills had been constructed in Cuba and Jamaica by the 1520s. The Portuguese took sugar cane to Brazil. By 1540, there were 800 cane-sugar mills in Santa Catarina Island and another 2,000 on

12430-762: Was grown. For example, in the 1790s Lieutenant J. Paterson, of the Bengal Presidency promoted to the British parliament the idea that sugar cane could grow in British India , where it had started, with many advantages and at less expense than in the West Indies . As a result, sugar factories were established in Bihar in eastern India. During the Napoleonic Wars , sugar-beet production increased in continental Europe because of

12543-550: Was highest in the United States, followed by Germany and the Netherlands. Brown and white granulated sugar are 97% to nearly 100% carbohydrates, respectively, with less than 2% water, and no dietary fiber, protein or fat (table). Brown sugar contains a moderate amount of iron (15% of the Reference Daily Intake in a 100 gram amount, see table), but a typical serving of 4 grams (one teaspoon), would provide 15 calories and

12656-459: Was more usually sold in bags. Sugar cubes were produced in the nineteenth century. The first inventor of a process to produce sugar in cube form was Jakob Christof Rad , director of a sugar refinery in Dačice . In 1841, he produced the first sugar cube in the world. He began sugar-cube production after being granted a five-year patent for the process on 23 January 1843. Henry Tate of Tate & Lyle

12769-479: Was the chief sugar refining and distribution center in Europe. There was a drastic change in the mid-15th century, when Madeira and the Canary Islands were settled from Europe and sugar introduced there. After this an "all-consuming passion for sugar ... swept through society" as it became far more easily available, though initially still very expensive. By 1492, Madeira was producing over 1,400,000 kilograms (3,000,000 lb) of sugar annually. Genoa , one of
