Question

Quizplus · Accepted Answer

The superior vena cava is not involved in pulmonary circulation. It returns deoxygenated blood from the upper body to the right atrium, but it does not pass through the lungs for exchange of gases. The left atrium receives oxygenated blood from the pulmonary veins after it has been oxygenated in the lungs. The right ventricle pumps deoxygenated blood through the pulmonary arteries to the lungs for gas exchange, and the pulmonary veins return oxygenated blood from the lungs to the left atrium.
