Explanation:
Detailed explanation-1: -Arteries have thicker smooth muscle layers to accommodate the changes in pressure from the heart. Arteries and arterioles have relatively thick muscular walls because blood pressure in them is high and because they must adjust their diameter to maintain blood pressure and to control blood flow.
Detailed explanation-2: -Arteries have a great deal more smooth muscle within their walls than veins, thus their greater wall thickness. This is because they have to carry pumped blood away from the heart to all the organs and tissues that need the oxygenated blood.
