Homeostasis is an organisms process of maintaining a stable internal environment suitable for sustaining life. Homeostasis is regulated by negative feedback loops and much less frequently by positive feedback loops.

Homeostasis is the activity of cells throughout the body to maintain the physiological state within a narrow range that is compatible with life.
Homeostasis definition anatomy. Homeostasis refers to the bodys ability to maintain a stable internal environment regulating hormones body temp water balance etc. This is achieved by attempting to maintain a constant internal state and all the systems of the body are involved in the effort. The word homeostasis derives from greek homeo meaning similar and stasis meaning stable when used as an adjective it is homeostatic.
Generally the body is in homeostasis when its needs are met and its functioning properly. Maintaining homeostasis requires that the body continuously monitors its internal conditions. A system used to control the level of a variable in which there is an identifiable receptor sensor control center integrator or comparator effectors and methods of communication.
Homeostasis the principle of self regulating information feedback by which constant conditions are maintained in a biological system such as the human body. Homeostasis is the dynamic equilibrium that maintains health within the body in spite of the continual changes taking place both internally and in the external environment. The biological definition of homeostasis is the tendency of an organism or cell to regulate its internal environment and maintain equilibrium usually by a system of feedback controls so as to stabilize health and functioning.
An example of homeostasis is the maintenance of a constant blood pressure in the human body through a series of fine adjustments in the normal range of function of the hormonal neuromuscular and cardiovascular systems. The maintenance of homeostasis in the body typically occurs through the use of feedback loops that control the bodys internal conditions. Homeostasis is a healthy state that is maintained by the constant adjustment of biochemical and physiological pathways.
These adjustments allow the maintenance of blood pressure needed for body function despite environmental changes and changes in a persons activity level. Homeostasis is essential to life and applies to thousands of bodily parameters.
