Explain how the following processes help maintain a constant body temperature in humans.
a. Shivering and Vasoconstriction: Shivering generates heat because to contract, the
muscles must carry out cellular respiration, releasing energy as heat. Vasoconstriction conserves
heat; it reduces the diameter of surface blood vessels and redirects blood to the body core, which
controls the temperature of the vital organs. This movement of blood toward the body core also
decreases the amount of heat loss through the skin
