Arteries carry blood (with oxygen) from your heart out to your body, while veins carry blood (without oxygen) from your body to your heart. Arteries are strong, flexible blood vessels that are able to expand (get bigger) and contract (get smaller). They expand as your heart beats, and contract between heartbeats. Veins are less flexible than arteries. They have valves (doors) that open and close to let blood through.
