Question

During exercise your body releases heat by

A)using stored energy
B) increasing breathing
C) decreasing heart rate
D) deilating blood vessels

Answer 1

D. Dilating blood vessels. This means that the blood vessels are expanding and coming closer to the surface (red face/skin) to release heat. Think of it like you spreading a hot meal over a larger area to cool off faster. In the same way, the blood vessels expand to cool off faster.
