Pulmonary arteries

This video tutorial by Matt from Kenhub focuses on the pulmonary arteries, which are unique as they carry deoxygenated blood from the right ventricle to the lungs for oxygenation. The main pulmonary artery branches into the left and right pulmonary arteries, directing blood to the respective lungs. After oxygenation, blood returns to the heart via pulmonary veins. The video encourages viewers to explore more anatomy resources on Kenhub.
