This is the word you are looking for Homeostasis
is the property of a system that regulates its internal environment and tends to maintain a stable, relatively constant condition of properties such as temperature or pH. It can be either an open or closed system. In simple terms, it is a process in which the body's internal environment is kept stable. It was defined by Claude Bernard and later by Walter Bradford Cannon in 1926,[3] 1929[4] and 1932.[5][6]
Typically used to refer to a living organism, the concept came from that of milieu intérieur that was created by Claude Bernard and published in 1865. Multiple dynamic equilibrium adjustment and regulation mechanisms make homeostasis possible.
Homeostasis needs to be distinguished from a simple dynamic equilibriums, which are not regulated, and steady states, which may be stable but sensitive to perturbations.
