Answer:
When oxygenated blood leaves the heart through the aorta, it travels to the body. The aorta is the largest artery in the human body, and it carries oxygenated blood from the left ventricle of the heart to the rest of the body. The aorta branches off into smaller arteries, which distribute the oxygenated blood to the various organs and tissues of the body. This allows the cells of the body to use the oxygen in the blood to produce energy and perform essential functions.
In contrast, deoxygenated blood returns to the heart through the veins, and is then pumped to the lungs where it is oxygenated. The oxygenated blood then returns to the heart through the pulmonary artery and is pumped out to the body through the aorta. This is known as the cardiovascular system, and it is essential for maintaining the oxygen supply to the cells of the body.
