 Place your response to this activity below. You will be marked according to your explanation of the body’s response to the two given situations. You must include references to vasoconstriction, vasodilation, countercurrent heat exchange, and peripheral heat loss.

Thermoregulation is the term used when biological systems attempt to maintain temperature. After watching the previous animations and reading the textbook, prepare a summary table. Outline the body’s thermoregulatory response to

•   an increase in internal temperature due to exertion
•   a colder external temperature than body temperature

Explain how peripheral heat loss, selective vasoconstriction, vasodilation, and countercurrent heat exchange are involved in each circumstance.

    Increased temperature (body)  due to exertion   T (body) > T (environment)
Peripheral heat loss      
Vasoconstriction/vasodilation      
Countercurrent exchange

Peripheral heat loss is regulated by controlling blood flow to specific regions of the body surface, which alters surface temperature

Vasoconstriction is the shrinking of blood vessels and vasodilation is the expansion of blood vessels so the skin can alter an organism's exchange of heat with the environment.

Countercurrent heat exchanger is an arrangement of blood vessels in which heat flows from warmer to cooler blood, usually reducing heat loss.
