Blood Flow and Thermoregulation

This interactive activity adapted from the University of Alberta explores heat exchange between the human circulatory system and the environment and illustrates how your body adapts its blood flow under different conditions. Animations show how peripheral heat loss, counter-current heat exchange, and selective vasoconstriction help maintain a healthy core body temperature.

This media asset was adapted from the University of Alberta.
