It is an ability of a cell to maintain of equilibrium condition within its internal environment and involves in maintaining of the constant environment in kidney, liver and skin.

Homeostasis is the process by which living organisms maintain a stable internal environment, despite changes in the external environment. It is a dynamic process that involves the regulation of various physiological processes, including body temperature, fluid balance, pH, and blood glucose levels, among others.

Homeostasis is critical for the survival and function of living organisms. Failure to maintain homeostasis can lead to various health problems, including dehydration, electrolyte imbalances, hypoglycemia, and other metabolic disorders.

The body maintains homeostasis through a variety of mechanisms, including feedback loops, which involve sensors, control centers, and effectors. Sensors detect changes in the internal or external environment, while control centers coordinate a response to restore balance. Effectors carry out the response, which can involve various physiological processes, such as hormone secretion, vasoconstriction or dilation, and changes in heart rate or respiration.

Homeostasis is maintained through a delicate balance of various physiological processes, and disruptions to this balance can have significant consequences. Therefore, understanding the mechanisms of homeostasis and how they are regulated is critical for maintaining optimal health and preventing disease.
