Question

Quizplus · Accepted Answer

The skin dissipates excess body heat through all of the given mechanisms: by dilating dermal blood vessels, activating eccrine sweat glands, and radiation. Dilating dermal blood vessels increases blood flow and thus facilitates heat loss through the skin surface, while activating eccrine sweat glands leads to the evaporation of sweat, which helps cool the skin. Radiation is also an essential mechanism for heat dissipation as the skin radiates heat into the surrounding environment. Therefore, all of the answer choices are correct.
