Deoxygenated blood from the body returns to the heart through veins. The heart then pumps the deoxygenated blood through pulmonary arteries to the lungs. In the lungs, the deoxygenated blood gets oxygen from air in the lungs, and the carbon dioxide is removed. The oxygenated blood is then returned to the heart through the pulmonary veins before being sent to the body through the main artery, the aorta.
