Vasoconstriction: the reduction in diameter of blood vessels, which helps to retain heat
Vasodilation: the expansion in diameter of blood vessels, which helps to release heat
Hypothalumus: a master coordinator region of the brain responsible for a variety of
physiological functions
Feedback loop: A pathway that includes input from a sensor, a response via an effector,
and detection of the response by the sensor
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
