Question

Quizplus · Accepted Answer

Sweating is the only heat-loss mechanism available to the body when the environmental temperature is so high that a normal temperature gradient between the skin and the environment cannot be established. Sweating causes evaporation of water from the skin surface, which cools the skin and results in heat loss. It does not cause vasodilation of the skin vessels or increase the insulative capacity of the skin.
