(= homoeostasis) The tendency towards a relatively constant state. A variety of homoeostatic mechanisms operate to keep the properties of the internal environment of organisms within fairly well-defined limits.
In medicine and biology, this term is applied to the inherent tendency in an organism toward maintenance of physiological and psychological stability.
Maintenance of constancy or a high degree of uniformity in functions of an organism or interactions of individuals in a population or community under changing conditions, because of the capabilities of organisms to make adjustments.
control of an organism`s internal environment. Water content, temperature, acid-base balance, level of oxygen and carbon dioxide, adequate supply of energy are some of the many factors in the organism which require monitoring and control. A common form of control is feedback.

Our body's natural state is one of internal balance or homeostasis. Regards flight or flight, when the danger is over the parasympathetic branch of our autonomic nervous system, antagonistic to the sympathetic branch, returns our body to its more natural state of homeostasis, or internal balance. Imagine what would happen without this!

The maintenance of constant internal conditions (mainly of the body fluids) in the face of changing activity and external conditions, to provide optimum conditions for enzyme activity of metabolism.
