Definition of vasodilation and vasoconstriction and their effect on resistance to blood flow. Introduction: In the cardiovascular system, change in the resistance to blood flow is mostly because of the radius of the blood vessels. Vascular resistance can be regulated in arteries and arterioles through the contraction (vasoconstriction) or relaxation (vasodilation) of the smooth muscle in the walls of the blood vessels. Usually, vasoconstriction increases resistance and vasodilation decreases resistance to blood flow.
