Endothermic Definition:
Humans and other mammals, as well as birds, are endothermic, meaning that they are warmed mostly by heat generated by metabolism.

Endothermic Notes:
An endotherm has the ability to maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic. If heat loss exceeds heat generation, metabolism increases to make up the loss or the animal shivers to raise its body temperature. If heat generation exceeds the heat loss, mechanisms such as panting or perspiring increase heat loss. Unlike ectotherms, endotherms can be active and survive at quite low external temperatures.
