Question

Quizplus · Accepted Answer

The right ventricle is the chamber of the heart that directly propels blood into the pulmonary circulation. The right atrium receives deoxygenated blood from the body and then sends it to the right ventricle, which then propels it out to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs and sends it to the left ventricle, which then propels it out to the rest of the body.
