Coronary arteries only

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: -Arteries carry fresh, oxygen-rich blood away from the heart to tissues throughout the body. Veins carry blood containing waste products such as carbon dioxide back through the heart to the lungs.
Detailed explanation-3: -The only artery that picks up deoxygenated blood is the pulmonary artery, which runs between the heart and lungs.
Detailed explanation-4: -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.
