Homeostasis
Constant temperature is needed in order
for biochemical reactions to occur at
certain rates
Heat Production: produced by the
metabolism of foods by muscles and
glands (liver)
Heat Loss: 80% occurs through the skin
Heat Loss: 80% occurs through the skin
Regulated by the vasoconstriction and
vasodialation of blood vessels
Heat can then be lost through evaporation,
radiation, conduction, and convection
