Answer: Pulmonary circulation is circulation to the lungs and back. It involves the pulmonary artery, pulmonary vein, the right ventricle, and the left atrium.
The pulmonary circulation is part of the circulation system that moves blood from the heart to the lungs and lungs to the heart.
Explanation:
The pulmonary circulation is the part of the circulatory system which carries deoxygenated blood away from the right ventricle, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart.
The deoxygenated blood is carried out by the right ventricle to the lungs and then moves the blood that carries the oxygen from the lungs to the left atrium and ventricle of the heart. It is a closed part of the circulation.
