<unk>   is the property of either an open system or a closed system, especially a living organism, that regulates its internal environment so as to maintain a stable, constant condition.  Multiple dynamic equilibrium adjustments and regulation mechanisms make<unk>  possible. The concept was created by Claude Bernard, often considered as the father of physiology, and published in 1865. The term was coined in 1932 by Walter Bradford Cannon from the Greek homoios (same, like, resembling) and stasis (to stand, posture).
