Detailed explanation-1: -The pulmonary circulation has many essential functions. Its primary function involves the exchange of gases across the alveolar membrane which ultimately supplies oxygenated blood to the rest of the body and eliminates carbon dioxide from the circulation.

Detailed explanation-2: -Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide.

Detailed explanation-3: -This deoxygenated blood is pumped into the lungs from the pulmonary valve. In the lungs, the deoxygenated blood is purified into oxygenated blood where the carbon dioxide is released. Finally, the oxygenated blood return to the heart through pulmonary veins where it is pumped all over the body.

Detailed explanation-4: -Your pulmonary arteries carry blood from your heart to your lungs. They’re the only arteries in your body that carry oxygen-poor (deoxygenated) blood. Your main pulmonary artery (pulmonary trunk) leaves your right ventricle at your pulmonary valve.
