Detailed explanation-1: -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.

Detailed explanation-2: -The pulmonary artery is an artery that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. The oxygenated blood from the lungs then enters the left side of the heart which pumps it to the rest of the body.
