There are many differences between arteries and veins. Both arteries and veins are blood vessels. Blood vessels are used to distribute blood throughout the body. There are three types of arteries, which are elastic arteries, arterioles, and muscular arteries. All three of these types have three coats, which are the outer, inner, and middle core. There are four types of veins, which include deep, systemic, superficial, and pulmonary veins.

Arteries don't have valves, while veins do. Arteries don't require valves because they use the pressure from the heart to keep blood flowing. They have to keep blood flowing to the heart. Arteries carry low oxygen blood, while veins carry blood that has oxygen.
