  1. homeostasis(n.)

    The ability and tendency of certain systems to maintain a relatively constant internal state in spite of changes in external conditions; this ability is achieved by the presence of feedback mechanisms which can adjust the state of the system to compensate for changes in the state caused by the external environment. It is exemplified in homeothermal biological systems, such as animals which maintain relatively constant blood temperature and composition in spite of variations in external temperature or the composition of the food ingested.

  1. Homeostasis

    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, 1929 and 1932. Typically used to refer to a living organism, the concept of homeostasis was preceded by that of milieu intérieur, defined by Claude Bernard and published in 1865. Multiple dynamic equilibrium adjustment and regulation mechanisms make homeostasis possible. Homeostasis needs to be distinguished from simple dynamic equilibriums, which are not regulated, and steady states, which may be stable but sensitive to perturbations.
