Their smooth muscle is less than arteries. Elastic fibers provide recoil which is what you need in arteries to propel the blood forward. Veins lack these which is why large amounts of blood can be stored in them without the walls providing any sort of recoil and keeping pressure low.elative to the walls of arteries, the veins' walls are thinner, because the pressure of the blood in the veins is much lower; so low in fact, that valves are required to prev â¦ ent blood in the veins flowing backwards.
