Veins are an important part of our circulatory system. They are responsible for returning deoxygenated blood back to the heart after arteries carry blood out. The vena cava is the largest vein in the body. Veins have much thinner walls than arteries... hence they are important part of body..

The arteries are perceived as carrying oxygenated blood to the tissues, while veins carry deoxygenated blood back to the heart. This is true of the systemic circulation, by far the larger of the two circuits of blood in the body, which transports oxygen from the heart to the tissues of the body. . . . .
