During exercise, which of the following is true about peripheral resistance to blood flow?

A. Skeletal muscle vasodilation decreases peripheral resistance to blood flow.
B. Vasodilation increases peripheral resistance to blood flow.
C. Vasoconstriction decreases peripheral resistance to blood flow.
D. Vasoconstriction increases peripheral resistance to blood flow.
E. None of the answers are correct.

Answer :

Vasodilation decreases peripheral resistance to blood flow.

What happens during exercise?

Skeletal muscles experience an increase in metabolic demands during exercise. The body adapts physiologically to fulfill these demands, including dilatation of blood vessels supplying the skeletal muscles. Vasodilation, more specifically arterioles, is the widening or relaxing of blood arteries.

On the other hand, vascular constriction describes the narrowing of blood vessels. Vasoconstriction would hinder blood flow and raise peripheral resistance. Vasodilation, however, is the predominant method used during exercise to maximize blood flow to the working muscles.
