Question

Quizplus · Accepted Answer

The right atrium receives deoxygenated blood from the systemic circuit and pumps it to the right ventricle, which then pumps the blood to the lungs for oxygenation through the pulmonary trunk. The aorta receives oxygen-rich blood from the left ventricle, while the left atrium receives oxygenated blood from the pulmonary circuit. The muscle tissue of the heart wall is not involved in receiving or pumping blood.
