Question
The hierarchy of priority for blood flow during prolonged exercise in the heat is:Group of answer choicesbrain > muscle > skinskin > brain > musclemuscle > brain > skin
Solution
The hierarchy of priority for blood flow during prolonged exercise in the heat is: brain > muscle > skin. This is because the brain is the most critical organ and requires a constant supply of oxygen and nutrients, which are delivered by the blood. The muscles are next in priority as they are actively working during exercise and need blood to deliver oxygen and remove waste products. The skin is last in priority as its main role during exercise in the heat is to help cool the body through sweating, which while important, is less critical than the needs of the brain and muscles.
