ANATOMY

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: -Veins carry blood containing waste products such as carbon dioxide back through the heart to the lungs.

Detailed explanation-3: -Pulmonary artery arises from right ventricle of heart. Right ventricle in turn receives blood from right atrium. Right atrium receives deoxygenated blood from all over the body through superior vena cava, inferior vena cava and coronary sinus. So, pulmonary artery receives deoxygenated blood from right side of heart.

Detailed explanation-4: -Pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation.

Detailed explanation-5: -Pulmonary artery carries deoxygenated blood to lungs for oxygenation. It is a large artery originating from the superior surface of right ventricle.
