Which structure pumps oxygen-rich blood to the body?

The left ventricle is the structure responsible for pumping oxygen-rich blood to the body. This chamber of the heart receives oxygenated blood from the left atrium, which has received it from the lungs via the pulmonary veins. The left ventricle then contracts, generating the necessary pressure to push the blood into the aorta, the main artery that distributes oxygenated blood to the entire body.

This process occurs after the blood has been oxygenated in the lungs and is critical for supplying oxygen and nutrients to the tissues. The strength of the left ventricle's contraction is essential for ensuring that blood reaches even the farthest extremities, making it one of the most muscular and powerful chambers of the heart.

In contrast, the right atrium collects deoxygenated blood returning from the body, the right ventricle pumps this deoxygenated blood to the lungs for oxygenation, and the pulmonary trunk carries deoxygenated blood from the right ventricle to the lungs. Therefore, the left ventricle's role in delivering oxygen-rich blood is central to maintaining the body's overall function and health.
