What is the Meaning & Definition of homeostasis

Homeostasis is the set of control parameters now consistency properties and the composition of the internal environment of the body. The concept was created by the American physiologist Walter Bradford Cannon (1871-1945). This term extends to biology to denote the characteristic of any kind of system, open or closed, allowing it to regulate the internal environment to maintain a stable condition. Stability makes possible by various mechanisms of regulation and several dynamic adjustments.
Homeostasis is one of the major principles of Physiology, given that if this feature fails, it may cause a malfunction of several organs.
Biological homeostasis is therefore a balanced dynamic that is achieved through constant changes to keep the result of the whole. This process includes the control of energy values to be normal: in case a value is outside the norm, several mechanisms are activated to compensate for.
The homeostasis of the body depends on the internal environment (with production and the elimination of certain substances; for example, through the urine) and the external environment (the relationship between living beings and the environment).
On the other hand, psychological homeostasis takes place through the balance between the needs and satisfaction. When needs are not satisfied, an internal imbalance occurs. The subject seeks to achieve balance by driving (behavior) provided to satisfy such needs.
Then cybernetic homeostasis is the ability of a cybernetic system to maintain certain variables within certain limits.
