Examples of organ in the following topics:
- 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 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.
- 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.
- 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.
sensory organs are able to sense
plasma molecules and pass that information into other regions of the
- These organs include:
- Vascular organ of lamina terminalis:
Responsible for the homeostatic
conservation of osmolarity.
- An organism is a living system capable of growth, reproduction,metabolism, response to stimuli, adaptation and homeostasis.
- Cells are the basic unit of life that can be found in every living organism.
- Multicellular organisms are typically made up of organ systems, organs, tissues, and cells.
- More complex organisms are capable of communication.
- Beyond these zones are the "zones of intolerance," where life for that organism is impossible.
- Vertebrates have fluid-filled spaces called body cavities that contain the organs.
- They usually contains protective membranes and sometimes bones that protect the organs.
- The organs within the ventral cavity are also called viscera.
- It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland.
- The abdominal cavity is not contained within bone and houses many organs of the digestive and renal systems, as well as some organs of the endocrine system, such as the adrenal glands.
- Lymphoid tissue consists of many organs that play a role in the production and maturation of lymphocytes in the immune response.
- The tissues of lymphoid organs are different than the tissues in most other organ systems in that they vary considerably based on cell cycle proliferation of lymphocytes.
- Central or primary lymphoid organs generate lymphocytes from immature progenitor cells such as lymphoblasts.
- Secondary or peripheral lymphoid organs maintain mature naive lymphocytes until an adaptive immune response is initiated.
- The lymph nodes organized around other lymph trunks, such as those in the abdomen and intestine, develop afterwards from nearby veins.
- It is distinguished from exteroception, perception of the outside
world, and interoception, perception of pain, hunger, and the movement of internal organs, etc.
- The Golgi organ (also called Golgi tendon organ, tendon organ, neurotendinous organ or neurotendinous spindle) is a proprioceptive sensory receptor organ that is located at the insertion of skeletal muscle fibers onto the tendons of skeletal muscle.
- The Golgi organ should not be confused with the Golgi apparatus—an organelle in the eukaryotic cell—or the Golgi stain, which is a histologic stain for neuron cell bodies.
- The Golgi tendon organ contributes to the Golgi tendon reflex and provides proprioceptive information about joint position.
- Systemic anatomy focuses on the anatomy of different organ systems, such as the respiratory or nervous system.
- Surface anatomy is also widely used to gauge the position and structure of deeper organs, tissues, and systems.
- Histology, the study of the organization and details of biological tissues
- The human body has many layers of organization.
- The history of anatomy has been an evolving understanding of organs and structures in the body.
- The male reproductive system includes external (penis, scrotum, epididymus, and testes) and internal (accessory) organs.
- The organs of the male reproductive system are specialized for three primary functions:
- The penis is the male organ for sexual intercourse and urination.
- The internal organs of the male reproductive system are called accessory organs.
