Answer:
Blood vessels dilate, resulting in heat loss to the surrounding.
Sweat glands secrete fluid. As the fluid evaporates, heat is lost from the body.
Explanation:
When the inner temperature becomes higher than the normal body temperature;
Blood vessels dilate, resulting in heat loss to the surrounding.
Sweat glands secrete fluid. As the fluid evaporates, heat is lost from the body.
In this way the body is able to maintain homeostasis following a rise in body temperature.
