Arteries and Veins are two different types of blood vessels in the circulatory system and are mainly involved in circulating blood throughout the body. However, the two blood vessels are quite different from each other in terms of function.
One of the major differences between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart with the exception of pulmonary arteries and veins.
