Question

when an athletes body temperature begins to climb, blood vessels in the skin dilate. as a result, the athletes face turns red because warm, oxygenated blood moves to the surface of the skin. this process helps to reduce overall body temperature and prevent overheating. which organ system most likely helps to keep an athlete from overheating? a. the digestive system b. the circulatory system c. the respiratory system d. the reproductive system

Explanation:

The text mentions that when an athlete's body temperature rises, blood vessels in the skin dilate and warm, oxygenated blood moves to the skin surface to reduce body - temperature. The circulatory system is responsible for the movement of blood throughout the body. The digestive system is for breaking down food, the respiratory system is for gas exchange, and the reproductive system is for reproduction. None of these are directly related to the process of preventing overheating by moving blood to the skin surface.

Answer:

B. the circulatory system
