Difference between Artery and vein.
Arteries are the blood vessels that carry blood away from the heart, where it branches into even smaller vessels. Finally, the smallest arteries, called arterioles are further branched into small capillaries, where the exchange of all the nutrients, gases and other waste molecules are carried out. Veins are the blood vessels present throughout the body. They are tube-like, translucent structures that function by carrying deoxygenated blood from the tissues to the heart for re-oxygenation. Compared to arteries, veins are thin-walled.
