Arteries need to be thick, muscular and elastic IN ORDER TO WITHSTAND THE PRESSURE OF THE BLOOD THAT IS BEING PUMPED BY THE HEART.

The walls of the arteries are thicker and more muscular than that of veins because of the work that they perform. The arteries have thick and muscular walls, which help them to withstand and absorb the pressure waves that are generated as a result of blood pumping from the heart. The elasticity of the arteries help them to generate appropriate pressure for supporting blood flow.
