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 circulation is the system of transportation that shunts de-oxygenated blood from the heart to the lungs to be re-saturated with oxygen before being dispersed into the systemic circulation.

Detailed explanation-3: -The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA). From there, the blood flows through the right and left pulmonary arteries into the lungs.

Detailed explanation-4: -Pulmonary vein carries deoxygenated blood to the lungs and pulmonary artery brings oxygenated blood towards the heart. (iv) sends oxygenated blood to all parts of the body through aorta.
