Quizplus · Accepted Answer

Pulmonary circulation starts with blood leaving the heart from the right ventricle (2), then moving to the pulmonary trunk (6), through the pulmonary arteries (4), into the pulmonary capillaries (5) where gas exchange occurs, then back to the heart via the pulmonary veins (3), and finally into the left atrium (1).
