The veins responsible for returning blood to the heart are the Superior and Inferior Vena Cava. Arteries send blood away from the heart, going from Arteries to Arterioles to Capillaries, then the return is from Capillaries to Venules to Veins. The Superior and Inferior Vena Cava are the veins that send blood to the right atrium after an entire blood circulation cycle.
Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. This differentiates the pulmonary veins from other veins in the body, which are used to carry deoxygenated blood from the rest of the body back to the heart
