Homeostasis

Homeostasis is a self-regulatory process through which different biological systems maintain constant internal environmental conditions to compensate for environmental changes. In human physiology, it is a process of self-regulating internal, chemical, and physical conditions at an optimal level for survival. The stability through homeostasis can be attained through dynamic equilibrium, in which there is a continuous change until it reaches its systemic conditions.
