Arterioles are the small branches of arteries that can contract or relax to control blood flow and resistance in the circulatory system. Veins and capillaries do not have a muscular layer and cannot actively control blood flow. While arteries can also constrict or dilate to adjust blood flow, arterioles are the primary regulators of resistance.
