Veins. Veins carry blood back to the heart. They carry deoxygenated blood away from the body. The blood returning from the body is at a much lower pressure than that being pumped from the heart. Therefore veins do not have to be as strong as arteries. Veins are wider than arteries and have much thinner walls.Look at the image below to see the main difference between arteries and veins.he blood returning from the body is at a much lower pressure than that being pumped from the heart.

Arteries carry blood away from the heart, while veins carry blood towards the heart. Capillaries carry blood from arteries to veins. Arteries generally carry oxygenated blood from the heart to the tissues and organs during the systolic heartbeat cycle. They are under high pressure. (the only exception is the pulmonary arteries which carries deoxygenated blood from the heart to the lungs).
