organ

Examples of organ in the following topics:

• Levels of Organization

  • Living organisms are made up of four levels of organization: cells, tissues, organs, and organ systems.
  • An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.
  • Most organs contain tissues such as parenchyma (used to perform the organ functions),  stroma (connective tissue specific to organs) and epithelial.
  • An organ system is a collection of organs that that work together to perform a similar function.
  • An organism contains organ systems made up of organs that consist of tissues, which are in turn made up of cells.

• Organ Transplants

  • Organ transplantation involves moving organs between bodies (or from donor sites on patients' bodies) for the purpose of replacing recipients' damaged or absent organs.
  • Tissue transplants occur much more frequently than organ transplants.
  • Organ donors may be living or brain dead.
  • Organ trafficking is one problem.
  • Organ transplants are not regulated by the FDA.

• Plant Tissues and Organ Systems

• Formal Structure

  • Formal structure of an organization or group includes a fixed set of rules for intra-organization procedures and structures.
  • Practical experience shows no organization is ever completely rule-bound: all real organizations represent some mix of formal and informal characteristics.
  • Tended effectively, the informal organization complements the more explicit structures, plans, and processes of the formal organization.
  • This deviation was referred to as informal organization.
  • A formal organization is a fixed set of rules of intra-organization procedures and structures.

• Flat versus tall organizations

  • By definition, a small business is typically a flat, centralized organization.
  • Flat organizations follow the decentralized approach, or organic system.
  • More decisions are made at the middle levels of the organization.
  • Internally, the organization as a whole encourages more participation between all levels of the organization.
  • A tall structure is a more formal, bureaucratic organization or mechanistic system.

• Layers in an Organization: Tall vs Flat Organizations

  • A tall organization is a more formal bureaucratic or mechanistic organizational structure and management system.
  • Tall organizations have several tiers in their structural hierarchy and multiple levels of management control with regard to the daily operations of the organization.
  • Flat organizations follow the decentralized approach or organic system of organization and management.
  • Internally, the organization as a whole encourages more participation between all levels within the organization, promoting closer working relationships that potentially lead to better communication and creativity.
  • Various factors, both internal (i.e. management style, culture, etc.) and external (i.e. competition, regulation, etc.) to the organization, influence what type of structure an organization assumes.

• Tissues in Levels of Organization

  • The next level is the organ system level.
  • Many organs working together to accomplish a common purpose create an organ system.
  • Cells form tissues, and tissues form organs.
  • Organs that fulfill related functions are called organ systems.
  • An organism is made up of interconnected organ systems.

• Development of Human Resources

  • Human resources development (HRD) as a theory is a framework for the expansion of human capital within an organization through the development of both the organization and the individual to achieve performance improvement.
  • Groups within organizations use HRD to initiate and manage change.
  • Organization development (OD), empowering the organization to take advantage of its human resource capital.
  • TD alone can leave an organization unable to tap into the increase in human, knowledge, or talent capital.
  • HRD does not occur without the organization, so the practice of HRD within an organization is inhibited or promoted upon the platform of the organization's mission, vision, and values.

• Growth Terminology

  • This reduction process forms an organic compound that stores chemical energy.
  • Autotrophs, and their formation of organic compounds, are an important component of the food chain because they produce the food necessary for larger, more complex organisms to grow.
  • Chemoautotrophs are thought to be the first organisms to inhabit earth.
  • A heterotroph is an organism that, unlike an autotroph, cannot fix carbon and uses organic carbon for growth.
  • These organisms use inorganic energy sources or organic energy sources to sustain life.

• Circumventricular Organs

  • Circumventricular organs are situated adjacent to the brain ventricles and sense concentrations of various compounds in the blood.
  • These organs secrete or are sites of action of a variety of different hormones, neurotransmitters, and cytokines.
  • These organs secrete or are sites of action of a variety of different hormones, neurotransmitters, and cytokines.
  • These organs include:
  • Vascular organ of lamina terminalis: Responsible for the homeostatic conservation of osmolarity.
