Muscular, or distributing, arteries deliver blood to specific body organs, and have the greatest proportion of tunica media of all vessels, making them more active in vasoconstriction. Arterioles are the smallest arteries and regulate blood flow into capillary beds through vasoconstriction and vasodilation.Capillaries are the smallest vessels and allow for exchange of substances between the blood and interstitial fluid.ntroduction to Blood Flow, Blood Pressure, and Resistance.
