How are blood vessels used in the circulatory system?
The blood vessels are hollow tubes that conduct blood from the heart to the body’s tissues and back again. There are three types: arteries, veins and capillaries. Arteries carry oxygenated blood away from the heart and to the tissues. The one exception to this is the pulmonary artery, which carries deoxygenated blood from the heart to the lungs.
