homeostasis
HOH-mee-oh-STAY-sis
/ˌhoʊmioʊˈsteɪsɪs/
The tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
It is a dynamic balance, not a static one; the body is constantly adjusting to stay the same.
The story behind the word. Coined by physiologist Walter Cannon in 1926. He combined 'homoios' (similar) and 'stasis' (standing still) to describe the body's 'wisdom' in keeping its internal environment steady.
