Path: If we start at the heart- blood travels thru arteries to all your organs. There the arteries become smaller and change into capillaries where oxygen is delivered and waste products from the cells removed. The capillaries then turn into veins which return the blood to the heart. There is a separate similar system from the heart to the lungs and back that brings oxygen into the body for distribution.
