D) vasoconstriction in skeletal muscle and vasodilation in viscera.

Question

Quizplus · Accepted Answer

During exercise, skeletal muscle requires more oxygen and nutrients, so there is vasodilation in skeletal muscle to increase blood flow. Meanwhile, there is vasoconstriction in the visceral organs as they do not require as much blood flow during exercise. This redistribution of blood flow allows for efficient delivery of oxygen and nutrients to the working muscles.
