Best Answer

Blood return to the right atrium of the heart through the superior and inferior vena cavae. Blood then travels to the right ventricle and leaves the heart through the pulmonary veins. The pulmonary veins lead to the lungs where blood is oxygenated. Oxygenated blood returns the left atrium of the heart via the pulmonary veins. Then blood travels to the left ventricle and leaves through the aorta.

The large veins that drain the body all come back to the heart and the large arteries that leave the heart all are attached to the heart and therefore the body.
