Question 16

In two to three sentences, describe how the integumentary system reacts to a rise in body temperature.

Answer 16

If the body gets too hot, the integumentary system uses homeostatic strategies to cool it off. Sweat is secreted by the sweat glands. As the water in sweat evaporates, the skin is cooled. Blood vessels also dilate and move closer to the skin surface to try and cool it.
