In a multicellular organism , an organ is a collection of tissues joined in a structural unit to serve a common function. In the hierarchy of life , an organ lies between tissue and an organ system . Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which has a specific function. The intestinal wall for example is formed by epithelial tissue and smooth muscle tissue . Two or more organs working together in the execution of a specific body function form an organ system, also called a biological system or body system.
53-564: The Bosnian Institute was an organization founded by Dr. Quintin Hoare in July 1997 and first registered on 7 October 1997, as a United Kingdom Registered Charity . The institute was based in London , and headed by Dr. Quintin Hoare, who was a joint founding editor with Branka Magaš of published quarterly online magazine called Bosnia Report . It was principally devoted to, "educate people throughout
106-399: A certain task can be fulfilled through a system of coordinated division of labor . Economic approaches to organizations also take the division of labor as a starting point. The division of labor allows for (economies of) specialization . Increasing specialization necessitates coordination. From an economic point of view, markets and organizations are alternative coordination mechanisms for
159-414: A cluster of institutions; the two are distinct in the sense that organizations contain internal institutions (that govern interactions between the members of the organizations). The study of organizations includes a focus on optimising organizational structure . According to management science , most human organizations fall roughly into four types: These consist of a group of peers who decide as
212-480: A collective actor?). By coordinated and planned cooperation of the elements, the organization is able to solve tasks that lie beyond the abilities of the single element. The price paid by the elements is the limitation of the degrees of freedom of the elements. Advantages of organizations are enhancement (more of the same), addition (combination of different features), and extension. Disadvantages can be inertness (through coordination) and loss of interaction . Among
265-463: A correct vote (however correctness is defined). The problem is that if the average member is subsequently worse than a roll of dice, the committee's decisions grow worse, not better; therefore, staffing is crucial. Parliamentary procedure, such as Robert's Rules of Order , helps prevent committees from engaging in lengthy discussions without reaching decisions. This organizational structure promotes internal competition . Inefficient components of
318-443: A group, perhaps by voting. The difference between a jury and a committee is that the members of the committee are usually assigned to perform or lead further actions after the group comes to a decision, whereas members of a jury come to a decision. In common law countries, legal juries render decisions of guilt, liability, and quantify damages; juries are also used in athletic contests, book awards, and similar activities. Sometimes

His need to identify with a community that provides security, protection, maintenance, and a feeling of belonging continues unchanged from prehistoric times. This need is met by the informal organization and its emergent, or unofficial, leaders. Leaders emerge from within the structure of the informal organization. Their personal qualities,
424-399: A manager may be confronted by an emergent leader who can challenge his role in the organization and reduce it to that of a figurehead. However, only the authority of position has the backing of formal sanctions. It follows that whoever wields personal influence and power can legitimize this only by gaining a formal position in the hierarchy, with commensurate authority. An organization that
477-418: A number of disciplines, such as sociology , economics , political science , psychology , management , and organizational communication . The broader analysis of organizations is commonly referred to as organizational structure , organizational studies , organizational behavior , or organization analysis. A number of different perspectives exist, some of which are compatible: Sociology can be defined as
530-459: A selection committee functions like a jury. In the Middle Ages, juries in continental Europe were used to determine the law according to consensus among local notables. Committees are often the most reliable way to make decisions. Condorcet's jury theorem proved that if the average member votes better than a roll of dice, then adding more members increases the number of majorities that can come to
583-416: A variety of organ systems . These specific systems are widely studied in human anatomy . The functions of these organ systems often share significant overlap. For instance, the nervous and endocrine system both operate via a shared organ, the hypothalamus . For this reason, the two systems are combined and studied as the neuroendocrine system . The same is true for the musculoskeletal system because of

689-668: A whole, are referred to as the Organon because logic is a tool for philosophical thinking. Earlier thinkers, such as those who wrote texts in the Hippocratic corpus , generally did not believe that there were organs of the body but only different parts of the body. Some alchemists (e.g. Paracelsus ) adopted the Hermetic Qabalah assignment between the seven vital organs and the seven classical planets as follows: Chinese traditional medicine recognizes eleven organs, associated with
742-668: Is "functional" and assures that each type of expert in the organization is well-trained, and measured by a boss who is a super-expert in the same field. The other direction is "executive" and tries to get projects completed using the experts. Projects might be organized by products, regions, customer types, or some other schemes. As an example, a company might have an individual with overall responsibility for products X and Y, and another individual with overall responsibility for engineering, quality control, etc. Therefore, subordinates responsible for quality control of project X will have two reporting lines. The United States aerospace industries were
795-473: Is a stronger form of influence because it reflects a person's ability to enforce action through the control of a means of punishment. As most organizations operate through a mix of formal and informal mechanisms, organization science scholars have paid attention to the type of interplay between formal and informal organizations. On the one hand, some have argued that formal and informal organizations operate as substitutes as one type of organization would decrease
848-614: Is an entity —such as a company , or corporation or an institution ( formal organization ), or an association —comprising one or more people and having a particular purpose. The word in English is derived from the Spanish organisation, which itself is derived from the medieval Latin organizationem and its root organum was borrowed whole from the Latin word organon , which means tool or instrument, musical instrument, and organ . There are
901-410: Is by merit or seniority. Each employee receives a salary and enjoys a degree of tenure that safeguards him from the arbitrary influence of superiors or of powerful clients. The higher his position in the hierarchy, the greater his presumed expertise in adjudicating problems that may arise in the course of the work carried out at lower levels of the organization. It is this bureaucratic structure that forms
954-495: Is established as a means for achieving defined objectives has been referred to as a formal organization . Its design specifies how goals are subdivided and reflected in subdivisions of the organization. Divisions, departments, sections, positions, jobs , and tasks make up this work structure . Thus, the formal organization is expected to behave impersonally in regard to relationships with clients or with its members. According to Weber's definition, entry and subsequent advancement
1007-406: Is the placenta , which has evolved more than 100 times independently in vertebrates, has evolved relatively recently in some lineages, and exists in intermediate forms in extant taxa. Studies on the evolution of the placenta have identified a variety of genetic and physiological processes that contribute to the origin and evolution of organs, these include the re-purposing of existing animal tissues,
1060-425: Is usually framed by formal membership and form (institutional rules). Sociology distinguishes the term organization into planned formal and unplanned informal (i.e. spontaneously formed) organizations. Sociology analyses organizations in the first line from an institutional perspective. In this sense, the organization is an enduring arrangement of elements. These elements and their actions are determined by rules so that

On the other hand, other scholars have suggested that formal and informal organizations can complement each other. For instance, formal mechanisms of control can pave the way for the development of relational norms. Organ (anatomy) An organ's tissues can be broadly categorized as parenchyma ,

For example, the gland 's tissue that makes the hormones is the parenchyma , whereas the stroma includes the nerves that innervate the parenchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wastes, and the connective tissues that provide a suitable place for it to be situated and anchored. The main tissues that make up an organ tend to have common embryologic origins, such as arising from
1908-443: The individual membership . Their objectives and goals may or may not coincide with those of the formal organization. The informal organization represents an extension of the social structures that generally characterize human life – the spontaneous emergence of groups and organizations as ends in themselves. In prehistoric times, man was preoccupied with his personal security, maintenance, protection, and survival. Now man spends
1961-468: The liver and heart evolved in the chordates about 550-500 million years ago, while the gut and brain are even more ancient, arising in the ancestor of vertebrates, insects, molluscs, and worms about 700–650 million years ago. Given the ancient origin of most vertebrate organs, researchers have looked for model systems, where organs have evolved more recently, and ideally have evolved multiple times independently. An outstanding model for this kind of research
2014-479: The monumental structure. So one can imagine that if the leader does not have the support of his subordinates, the entire structure will collapse. Hierarchies were satirized in The Peter Principle (1969), a book that introduced hierarchiology and the saying that "in a hierarchy, every employee tends to rise to his level of incompetence." In the social sciences, organizations are the object of analysis for
2067-467: The new generation of plants (see clonal colony ). Many societies have a system for organ donation , in which a living or deceased donor's organ are transplanted into a person with a failing organ. The transplantation of larger solid organs often requires immunosuppression to prevent organ rejection or graft-versus-host disease . There is considerable interest throughout the world in creating laboratory-grown or artificial organs . Beginning in
2120-403: The opposing sides. Aristotle used the word frequently in his philosophy, both to describe the organs of plants or animals (e.g. the roots of a tree, the heart or liver of an animal) because, in ancient Greek, the word ' organon ' means 'tool', and Aristotle believed that the organs of the body were tools for us by means of which we can do things. For similar reasons, his logical works, taken as

The less-advanced taxa (i.e. Placozoa , Porifera , Ctenophora and Cnidaria ) do not show consolidation of their tissues into organs. More complex animals are composed of different organs, which have evolved over time. For example,

In other divisions ( phyla ) of plants, the reproductive organs are called strobili , in Lycopodiophyta , or simply gametophores in mosses . Common organ system designations in plants include the differentiation of shoot and root. All parts of the plant above ground (in non- epiphytes ), including the functionally distinct leaf and flower organs, may be classified together as

Companies that utilize this organization type reflect a rather one-sided view of what goes on in ecology . It is also the case that a natural ecosystem has a natural border – ecoregions do not, in general, compete with one another in any way, but are very autonomous. The pharmaceutical company GlaxoSmithKline talks about functioning as this type of organization in this external article from The Guardian . By:Bastian Batac De Leon. This organizational type assigns each worker two bosses in two different hierarchies. One hierarchy

In the study of anatomy , viscera ( sg. : viscus ) refers to the internal organs of the abdominal , thoracic , and pelvic cavities . The abdominal organs may be classified as solid organs or hollow organs . The solid organs are the liver , pancreas , spleen , kidneys , and adrenal glands . The hollow organs of the abdomen are
2438-534: The same germ layer . Organs exist in most multicellular organisms . In single-celled organisms such as members of the eukaryotes , the functional analogue of an organ is known as an organelle . In plants, there are three main organs. The number of organs in any organism depends on the definition used. There are approxiamately 79 Organs in the human body,but it is something that is debated as not all scientist agree on what counts as an organ. Except for placozoans , multicellular animals including humans have
2491-489: The same time, a second meaning arose, in reference to a "body part adapted to a certain function". Plant organs are made from tissue composed of different types of tissue. The three tissue types are ground, vascular, and dermal. When three or more organs are present, it is called an organ system. The adjective visceral , also splanchnic , is used for anything pertaining to the internal organs. Historically, viscera of animals were examined by Roman pagan priests like
2544-410: The science of the institutions of modernity ; specific institutions serve a function , akin to the individual organs of a coherent body. In the social and political sciences in general, an "organization" may be more loosely understood as the planned, coordinated, and purposeful action of human beings working through collective action to reach a common goal or construct a tangible product . This action
2597-409: The shoot organ system. The vegetative organs are essential for maintaining the life of a plant. While there can be 11 organ systems in animals, there are far fewer in plants, where some perform the vital functions, such as photosynthesis , while the reproductive organs are essential in reproduction . However, if there is asexual vegetative reproduction , the vegetative organs are those that create
2650-533: The spokesperson of a group of people subject to negotiation (e.g.: the Polisario Front being recognized as the sole representative of the Sahrawi people and forming a partially recognized state .) Compare the concept of social groups , which may include non-organizations. Organizations and institutions can be synonymous, but Jack Knight writes that organizations are a narrow version of institutions or represent
