homeostasis

[hō′mē·əstā′sis]

Etymology: Gk, homoios + stasis, standing still

a relative constancy in the internal environment of the body, naturally maintained by adaptive responses that promote healthy survival. Various sensing, feedback, and control mechanisms function to effect this steady state. Some of the key control mechanisms are the reticular formation in the brainstem and the endocrine glands. Some of the functions controlled by homeostatic mechanisms are heartbeat, hematopoiesis, blood pressure, body temperature, electrolytic balance, respiration, and glandular secretion. homeostatic, adj.

homeostasis,

n the state of balance in the internal environment of the body achieved by various control mechanisms.

homeostasis (hō´mēōstā´sis),

n the term used to describe the tendency toward physiologic equilibration (e.g., acid-base balance, pH level of blood, blood sugar level).

homeostasis, cell,

n the tendency of biologic tissues and processes to maintain a constancy of environment consistent with their vitality and well being. For cells to maintain their stability or equilibrium, the cell membranes must be in continuous interaction with both the internal (intracellular) environment and the external (extracellular) environment. When the equilibrium of any component is disturbed, the interaction permits automatic readjustment by giving rise to stimuli that result in restoration of the equilibrium.

homeostasis

a tendency of biological systems to maintain stability while continually adjusting to conditions that are optimal for survival.

Homeostatic mechanisms are necessary for the body to regain its balance when disease or injury occurs and to maintain that balance if it is to remain healthy.
