Which of the following is least involved in pulmonary circulation?

Explanation:
Pulmonary circulation moves blood between the heart and lungs. The right ventricle pumps blood into the pulmonary trunk and arteries, it travels through pulmonary capillaries in the lungs for gas exchange, and returns to the heart through the pulmonary veins into the left atrium. Those components are all part of the pulmonary circuit. Systemic arteries, on the other hand, belong to the circulation that supplies the rest of the body and do not participate in the lung-side circuit. Because of that, systemic arteries are least involved in pulmonary circulation.
