Explain how the body maintains its constant normal temperature of 98.6° F
The cells of each organ conduct metabolic activities specific to that organ. In addition, all cells must maintain themselves, and many must reproduce. To do this, they must have all the essential nutrients available to them: energy nutrients, vitamins, and minerals, as well as water. As cells do their metabolic work, the chemical reactions that are involved release heat, and this heat keeps the body warm. By regulating the rates at which these metabolic reactions release heat energy, the body maintains its constant normal temperature of about 98.6°F.
