What controls the diameter of the arterioles and what do changes in diameter affect?
Arterioles are the smallest vessels of the arterial system, with a diameter of about 1/3 millimeter or smaller.

Such vasoconstriction and vasodilation plays two important roles in the cardiovascular system.controls of distribution of blood flow to different parts of the bodydetermines the total peripheral resistance
