Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
Generally most veins carry deoxygenated blood. Arteries carry oxygenated blood. The correct way to think about it is that Veins carry blood to the heart, whilst arteries carry blood away from the heart.This means in most cases, the blood carried by veins will be deoxygenated, whilst the blood carried by arteries is oxygenated.n this case the pulmonary artery carries deoxygenated blood to the lungs, whilst the pulmonary vein carries oxygenated blood from the lungs back to the heart to be pumped to the rest of the body.
