Quizplus · Accepted Answer

Shunting during exercise has the dramatic effect of increasing blood flow to the working skeletal muscles from about 20% of total cardiac output to 85% during high intensity exercise. This is accomplished by the vasoconstriction of vessels around organ systems and the concurrent vasodilation of the vessels in the muscles.
