Heat production is an essential feature of life. As has already been indicated, the heat loss from the body is a measure of its energy exchange and is a result of the chemical changes which are an essential part of the living process. In the warm – blooded animal this production of heat also serves to maintain the body at a constant temperature (36 – 37⁰ C; 97 – 99⁰ F) which is usually above that of the environment. The maintenance of this constancy is one of the important homeostatic mechanisms of the body. Since the heat production exceeds that which is necessary for maintaining the body Read more
