Blood vessels are a series of tubes inside your body. They move blood to and from your heart. Arteries carry blood away from the heart and transport oxygen and useful nutrients to the body's cells. After the oxygen has been used up, veins take blood back to the heart where it is pumped to the lungs to pick up new oxygen again.
