areteries pump blood around the body, and are ticker so they can with stand the pressure that is used to pump the bloody from the heart to muscles and organs around the body. where as veins are thiner and have valves on them to stop back flow as these are the ones that take blood back to the heart from around the body, via the lungs, when it is deoxygenated to pick up more oxygen then be pumped back around the body again, via the areteries..
hope that helps..

This is because arteries have more force going through them than veins do. Arteries have a higher level of pressure as opposed to veins who are more relaxed and just have blood being pushed along through them rather than FORCED. If you put a vein in place of an artery, it would probably just burst.
