Functionally, why are there no valves in arteries (as opposed to in veins)? valves only direct blood toward the heart and arterial blood passes away from the heart, valves would tear apart from the high arterial pressure, since arteries get more atherosclerosis valves would cause lethal blood clotting, the blood pressure in arteries is high enough that there is no back-flow of blood

the blood pressure in arteries is high enough that there is no back-flow of blood
