PATHOLOGY

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: -Explanation: The pulmonary arteries are the only arteries that contain oxygen-poor blood because it carries blood into the lungs to be oxygenated. By definition, arteries carry blood away from the heart and veins carry blood to the heart.

Detailed explanation-3: -The function of the pulmonary arteries is to transport the deoxygenated blood to the lungs where it can be reoxygenated through diffusion. They are still called arteries because they transport blood away from the heart, regardless of whether or not the blood is deoxygenated or oxygenated.
