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: -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-3: -Generally an artery carries oxygenated or pure blood in the body and veins carry deoxygenated or impure blood. But pulmonary artery is the only artery which carries impure or deoxygenated blood and pulmonary vein carries impure blood.

Detailed explanation-4: -Arteries carry oxygenated blood away from the heart (except for the pulmonary artery which carries deoxygenated blood away from the right ventricle to the lungs). The main artery is the aorta.

Detailed explanation-5: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
