Only the pulmonary veins return oxygenated blood from the lungs to the left atrium of the heart. The pulmonary arteries, on the other hand, carry deoxygenated blood from the heart to the lungs for oxygenation. The superior and inferior vena cava return deoxygenated blood from the systemic circulation to the right atrium of the heart, while the aorta carries oxygenated blood from the left ventricle to the body's tissues.
