What is the dictionary definition of homeostasis?
What is the dictionary definition of homeostasis?
the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function.
What is homeostatic physiology?
Homeostasis refers to the body’s ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.). From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point.
What is proliferation in cell biology?
(sel proh-LIH-feh-RAY-shun) An increase in the number of cells as a result of cell growth and cell division.
What are homeostatic functions?
The purpose of homeostasis is to maintain a normal balance within the body regarding its temperature, salt concentration, water concentration, and food intake. The human body functions normally with a narrow range of variation for each of these factors.
What is the purpose of the homeostatic system?
In short, the purpose of homeostasis is to maintain the established internal environment without being overcome by external stimuli that exist to disrupt the balance.
What is proliferation and differentiation?
The key difference between cell proliferation and differentiation is that cell proliferation is the process of increasing the cell number while cell differentiation is the process of forming a variety of cell types that have specific functions.
What is the meaning of homeostasis in biology?
Homeostasis Definition. Homeostasis is an organism ’s process of maintaining a stable internal environment suitable for sustaining life. The word homeostasis derives from Greek, with home meaning “similar,” and stasis, meaning “stable.”. When used as an adjective, it is homeostatic.
What is the meaning of the word homostatic?
dictionary thesaurus. noun. ho·meo·sta·sis | \\ˌhō-mē-ō-ˈstā-səs \\. : a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group striving to achieve homeostasis.
What is homeostatic regulation of body temperature?
In human beings, the homeostatic regulation of body temperature involves such mechanisms as sweating when the internal temperature becomes excessive and shivering to produce heat, as well as the generation of heat through metabolic processes when the internal temperature falls too low.

What is feedback homeostasis?
Relating to homeostasis. The state of dynamic equilibrium of the internal environment of the body that is maintained by the ever-changing processes of feedback and regulation in response to external or internal changes. Synonym: dynamic equilibrium See: Negative Feedback (Homeostasis) Want to thank TFD for its existence?
