n.
A state of equilibrium, as in an organism or cell, maintained by self-regulating processes: The kidneys maintain homeostasis in the body by regulating the amount of salt and water excreted.

ho′me·o·stat′ic (-stăt′ĭk) adj.

homeostasis

(ˌhəʊmɪəʊˈsteɪsɪs) or

homoeostasis

n
1. (Physiology) the maintenance of metabolic equilibrium within an animal by a tendency to compensate for disrupting changes
2. the maintenance of equilibrium within a social group, person, etc
homeostatic, homoeostatic adj

ho•me•o•sta•sis

(ˌhoʊ mi əˈsteɪ sɪs)

n.
1. the tendency of a system, esp. the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus tending to disturb its normal condition or function.
2. a state of psychological equilibrium obtained when tension or a drive has been reduced or eliminated.

ho·me·o·sta·sis

(hō′mē-ō-stā′sĭs)
The tendency of an organism or cell to regulate the chemical processes that take place internally so as to maintain health and functioning, regardless of outside conditions. The ability to maintain a steady body temperature is an example of homeostasis.

homeostasis

1. Maintenance of a stable internal environment inside an organism.
2. The body’s internal balance, produced by a regulatory system that maintains more or less stable temperature, blood pressure, electrolyte levels, etc.
