The part of the circulatory system that delivers blood back to the heart is the venous system, specifically the veins. Veins carry deoxygenated blood from the body back to the heart, with the major veins being the superior and inferior vena cavae, which empty into the right atrium of the heart. In the case of pulmonary circulation, the pulmonary veins transport oxygenated blood from the lungs back to the left atrium of the heart.
