The walls of arteries are composed of muscle which allows the artery to widen or narrow so as to control blood pressure within.
Veins have little one way valves in them to keep blood moving in one direction only. Blood in veins is under not much pressure wheras blood in arteries is under much more pressure as this blood has just been pumped by the heart.
