Answer:
Arteries carry blood away from the heart, and veins carry blood toward the heart, but that is not the only difference. Arteries and veins differ in their structure as well. ... Arteries and veins are similar in that the layers which form the walls are similar in composition. The innermost layer is the tunica intima.Arteries have very thick walls to withstand very high pressure as oxygenated has more pressure than deoxygenated ones. Meanwhile, veins have thin walls. Veins have valves present inside them to prevent the back flow of the bloods and arteries do not have one.
