During maximal exercise, blood flow decreases to all the following organs EXCEPT:
  1. Skeletal muscle
  2. Liver
  3. Brain
  4. Kidneys
Explanation
Answer: A - During intense physical activity, blood is diverted to the active skeletal muscle, increasing its distribution from 15-20% to 84%. Cardiac output to the brain, kidneys, gastrointestinal tract, and skin (during maximal exercise) decreases during exercise. The percentage of cardiac output to the coronary arteries at rest and during maximal exercise remains the same.
