Which of the following is least involved in pulmonary circulation?

Question

Quizplus · Accepted Answer

The superior vena cava brings deoxygenated blood from the upper part of the body to the right atrium, which is then pumped by the right ventricle to the pulmonary arteries and then to the lungs for oxygenation. The oxygenated blood returns to the heart via pulmonary veins and enters the left atrium, which pumps it to the left ventricle for distribution to the rest of the body. Therefore, all the other choices (A, C, and D) are involved in pulmonary circulation except for the superior vena cava (B).
