Which chamber receives oxygenated blood from the pulmonary veins and pumps it into systemic circulation?

Explanation:
Oxygenated blood from the lungs returns to the heart through the pulmonary veins and enters the left atrium. From there, blood moves to the left ventricle, which then pumps it into the systemic circulation via the aorta. The left atrium’s job is to receive that oxygenated blood from the pulmonary veins, and it passes it on to the ventricle that powers the body's-wide circulation. The right-sided chambers handle deoxygenated blood and the left ventricle is the main pump for systemic flow, receiving blood from the left atrium rather than directly from the pulmonary veins.
