Question

Quizplus · Accepted Answer

Perspiration cools the body by the evaporation of water from the sweat glands on the surface of the skin. Merocrine sweat glands are responsible for producing the most sweat, and therefore the greatest cooling effect. Apocrine sweat glands produce a thicker, oilier sweat that doesn't evaporate as easily and does not contribute as much to cooling the body. Retention of water from either type of sweat gland would not result in cooling of the body.
