Homeostasis
Homeostasis (from Greek: ὅμοιος, hómoios, "similar" and στάσις, stásis, "standing still";) is the property of a system that regulates its internal environment and tends to maintain a stable, constant condition of properties like temperature or pH. It can be either an open or closed system.
It was defined by Claude Bernard and later by Walter Bradford Cannon in 1926, 1929 and 1932)
Typically used to refer to a living organism, the concept came from that of milieu interieur that was created by Claude Bernard and published in 1865. Multiple dynamic equilibrium adjustment and regulation mechanisms make homeostasis possible.
