During exercise_____________?
Correct answer: B. Body temperature increases
- A. Cerebral blood flow increases if there is increase in systolic blood pressure
- B. Body temperature increases
- C. Blood flow to muscle increases after 1½ minute
- D. Lymphatic flow from muscle decrease
Explanation
Exercise increases heat production, so body temperature rises. Cerebral blood flow is autoregulated rather than simply increasing with systolic pressure, muscle blood flow rises earlier than 1½ minutes, and lymphatic flow increases.
