Which chamber pumps oxygenated blood to the body?

The left ventricle is the chamber that pumps oxygenated blood to the body. It receives oxygen-rich blood from the left atrium and then contracts to eject it into the aorta, which distributes it throughout the systemic circulation. Its thick muscular wall provides the high pressure needed to push blood through the entire body. The other chambers have different roles: the right atrium collects deoxygenated blood from the body, the left atrium collects oxygenated blood from the lungs (but does not send it to the body), and the pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.
