Question

Quizplus · Accepted Answer

When exposed to extreme heat, the human body relies on evaporation to absorb excess calories of heat and maintain normal body temperature. Evaporation occurs when sweat (which is mostly water) is secreted from sweat glands and then evaporates from the surface of the skin. This process requires energy, which is taken from the excess heat in the body, thus reducing body temperature. Condensation, respiration, and transpiration do not play significant roles in regulating body temperature in response to extreme heat.
