Detailed explanation-1: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.
Detailed explanation-2: -The right pulmonary artery supplies the right lung while the left pulmonary artery supplies the left lung. The right pulmonary artery courses posterior to the ascending aorta and anterior to the descending aorta. It lies anterior to the right mainstem bronchus.
Detailed explanation-3: -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.
