PATHOLOGY

Detailed explanation-1: -What are the pulmonary arteries? Your pulmonary arteries are blood vessels that carry oxygen-poor blood from the right side of your heart to your lungs. In medical terms, the word “pulmonary” means something that affects your lungs.

Detailed explanation-2: -Right superior pulmonary vein: Drains your right lung’s upper lobe and middle lobe. Right inferior pulmonary vein: Drains your right lung’s lower lobe. Left superior pulmonary vein: Drains your left lung’s upper lobe and your lingula (often called the “tongue” in your left lung).

Detailed explanation-3: -The left pulmonary artery is one of the branches of the pulmonary trunk, branching at the level of the transthoracic plane of Ludwig. It is shorter than the right pulmonary artery and represents a direct posterior continuation of the pulmonary trunk.
