Which chamber pumps deoxygenated blood to the lungs?

Explanation:
Pumping deoxygenated blood to the lungs is the job of the right ventricle. It receives blood from the right atrium through the tricuspid valve and then contracts to push that blood into the pulmonary artery via the pulmonary valve, directing it to the lungs for oxygenation. This chamber is part of the pulmonary circulation, which operates at lower pressures than the left-sided, systemic side of the heart. In contrast, the left atrium handles oxygenated blood returning from the lungs, and the left ventricle pumps that oxygen-rich blood out to the rest of the body. The right atrium collects deoxygenated blood from the body but does not send it to the lungs—that function belongs to the right ventricle.
