Which heart chamber pumps oxygenated blood to the body?

Explanation:
The key idea is how the heart’s two pumps handle different circulations. The left ventricle is the chamber that drives blood to the body. After oxygenated blood returns from the lungs to the left atrium and passes into the left ventricle, the left ventricle contracts powerfully to push that blood into the aorta and out to all tissues. Its thick, muscular wall is built for generating the high pressure needed for systemic circulation. In contrast, the right ventricle sends blood to the lungs for oxygenation, the left atrium collects oxygenated blood from the lungs but does not pump it to the body, and the right atrium collects deoxygenated blood from the body. So the chamber that pumps oxygenated blood to the body is the left ventricle.
