The aorta stretches across the back of your heart and pumps blood both above and below your heart to your upper and lower body
As oxygenated blood goes to your cells, it drops off oxygen and picks up waste
Cells in your body need oxygen so that they can perform cellular respiration to get energy
Blood also picks up carbon dioxide from the cells as the waste product of cellular respiration

Blood enters the heart through veins called the superior and inferior vena cava into the right atrium. The blood passes through the tricuspid valve into the right ventricle, where it is pushed past the pulmonary valves into the pulmonary arteries to the lungs. The blood then comes back to the heart via the pulmonary veins into the left atrium. The blood then passes though the bicuspid valve into the left ventricle, where it is pushed though the aortic valves into the aorta, which carries it to the rest of the body.
