homoeostasisn.

/hɒmiːˈɒstəsɪs/

/hɒmiːəʊˈsteɪsɪs/

Inflections: Also homeostasis;

Etymology: modern Latin, < homoeo- comb. form + Greek στάσις standing still, stationariness.

The maintenance of a dynamically stable state within a system by means of internal regulatory processes that tend to counteract any disturbance of the stability by external forces or influences; the state of stability so maintained; spec. in Physiology, the maintenance of relatively constant conditions in the body (e.g. as regards blood temperature) by physiological processes that act to counter any departure from the normal.
