MICROANATOMY

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: -The only artery that picks up deoxygenated blood is the pulmonary artery, which runs between the heart and lungs.

Detailed explanation-3: -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.
