Web4 Summary. Thermoregulation is the maintenance of a stable body temperature by managing the flow of heat into and out of the body. Although there are two major strategies, exothermy (relying on external heat sources) and endothermy (relying on internally generated heat), all animals use a combination of behavioral and physiological strategies ...
