explain the role of Homeostasis.?

Homeostasis, in biological terms means that the body is maintaining internal equilibrium to adjust itself internally and physiologically, in response to the external environmental changes. The main function of homeostasis is to keep all the processes of the body stable even if there are variations in the weather and environment outside. To maintain homeostasis means that the body is responding internally to the changes outside by maintaining the proper functioning of our internal organs. Homeostasis is the reason why, human beings can function efficiently in cold as well as hot environments. Animals, humans, other mammals and birds, who can maintain the temperature of the internal environment even though there may be large changes in the environmental temperature are called homeotherms. Regulation of blood pressure, temperature, blood sugar levels, hormone levels, and enzyme levels are all a part of homeostatic processes in the human body. Problems with any of these processes can lead to serious health hazards.
