What is pulmonary circulation?

Pulmonary Circulation is part of the Cardiovascular system in which it carries oxygen depleted blood away from the heart and to the lungs and returns oxygenated blood back to the heart. Deoxygenated blood exits the heart through the pulmonary arteries and enters the lungs and oxygenated blood comes back through pulmonary veins. The blood moves from right ventricle of the heart to the lungs back to the left atrium.
