Question

Which of the following are involved in the pulmonary circuit?
A) superior vena cava, right atrium, left ventricle
B) right ventricle, pulmonary veins, aorta
C) right ventricle, pulmonary trunk, left atrium
D) inferior vena cava, right atrium, aorta
E) left ventricle, pulmonary veins, right atrium

The pulmonary circuit involves the right ventricle pumping deoxygenated blood through the pulmonary trunk to the lungs, where oxygenation occurs, and then returning oxygenated blood to the left atrium. Therefore, the correct choice is C, which includes the right ventricle, pulmonary trunk, and left atrium.
