Final answer:
Oxygen-rich blood is pumped from the left ventricle into the aorta, which then distributes it throughout the body.
Step-by-step explanation:
Oxygen-rich blood flows from the left ventricle before the aorta carries it to the body. The process begins with the pulmonary veins bringing oxygen-rich blood to the left atrium. Next, the blood moves to the left ventricle, which pumps it through the aortic valve into the aorta.
From there, the aorta branches into smaller arteries, which carry the oxygenated blood to various parts of the body. After delivering oxygen to the tissues through capillaries, the now oxygen-depleted blood returns to the heart via the venous system to complete the systemic circulation.
