What part of the heart is responsible for pumping oxygenated blood to the body?

The left ventricle is responsible for pumping oxygenated blood to the body. This chamber of the heart receives oxygen-rich blood from the left atrium, which gets the blood from the lungs through the pulmonary veins. Once filled, the left ventricle contracts powerfully, propelling the oxygenated blood through the aorta and into systemic circulation.

The thick muscular walls of the left ventricle enable it to create enough pressure to distribute blood throughout the entire body, ensuring that all tissues receive the oxygen and nutrients needed for proper function. This contrasts with the other chambers of the heart; for instance, the right atrium and right ventricle handle deoxygenated blood coming from the body and sending it to the lungs for oxygenation.
