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.

There are two types of blood vessels: arteries and veins. Arteries carry blood under high pressure out to all areas of the body after being pumped by the heart. Veins carry blood that should be under low pressure, on its way back to the heart. An artery does not usually connect directly to a vein.Usually there are very small blood vessels called capillaries that connect an artery to a vein.. Source(s): http://www.hht.org/web/what_is_hht/overv...ere the blood in the capillaries gives oxygen to the cells and picks up the waste gas, carbon dioxide, from the cells. The capillaries are connected to the smallest veins in the body. The veins get bigger and bigger as they carry the blood back towards the heart.
