Which chamber of the heart pumps blood to the body?

Explanation:
Pumping blood to the body requires generating enough pressure to push blood through the systemic circulation. The chamber that does this is the left ventricle, because it ejects oxygenated blood into the aorta with enough force to reach all body tissues. Its thick muscular wall is built for high-pressure output, matching the demands of circulating blood systemically. By contrast, the right ventricle sends blood to the lungs at a much lower pressure, the left atrium collects oxygenated blood from the lungs, and the right atrium collects deoxygenated blood from the body. So, the left ventricle is the chamber that drives blood to the body.
