Veins are a part of the human cardiovascular system. There job is to return blood back to the heart after the blood has circulated through the body by way of the arteries. The arteries, which carry the blood away from the heart, eventually divide into small capillaries, or tiny blood vessels, which diffuse oxygen originally from the heart into body cells. That blood then picks up wastes (including Co2) from those cells and returns to the heart through the veins of the body. The veins are found in all parts of our body. Some of the largest veins are the superior and inferior vena cava which are the last channels before oxygen-depleted blood reaches the heart. The jugular is the main vein that brings blood back from the brain.
Pulmonary veins are the exceptional veins because they are the only veins that transport oxygenated blood back to the heart. In the lungs, oxygen is diffused into small capillaries that branch off from one of the four pulmonary veins. The oxygenated blood in the pulmonary veins then enters the heart where it's later pumped back out of the heart again through the aorta (artery).

∙ 13y agoVeins are the blood vessels that transport blood to the heart. Throughout most of the body, veins carry unoxygenated blood, but that is not always the case, because the pulmonary vein takes blood from the lungs to the heart. Arteries take blood from the heart, veins take it back.
