The pulmonary vein transports oxygenated blood back to the right atrium from the lungs.
I think its the heart, left and right ventricles, right atrium, aorta, left pulmonary artery right pulmonary artery, left pulmonary vein and right pulmonary vein. These are eight main parts.
The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart
The pulmonary vein carries blood from the lungs to the right atrium. This blood is oxygen-rich.
there are two right pulmonary veins right inferior pulmonary vein: the vein returning oxygenated blood from the inferior lobe of the right lung to the left atrium; tributaries include the superior vein and the common basal vein from the right inferior lobe. Syn: vena pulmonalis inferior dextra right superior pulmonary vein the vein returning oxygenated blood from the superior and middle lobes of the right lung to the left atrium; tributaries include apical anterior and posterior veins (branches) from the right superior lobe and the middle lobe vein. Syn: vena pulmonalis superior dextra

Pulmonary trunk
The pulmonary artery takes blood from the right ventricle into the lungs; the pulmonary vein collects blood from the lungs back to the left atrium of the heart.
pulmonary vein
The right pulmonary vein brings oxygenated blood from the lungs to the left atrium of the heart.
The PULMONARY vein. Pulmonary = lungs. Vein = ALWAYS carries blood TO the heart.
Artery - always carries blood FROM the heart Vein - always carries blood TO the heart The vein which brings blood to the heart from the lungs is the PULMONARY VEIN ('pulmonary' = lungs). The one carrying blood away from the heart to the lungs is the pulmonary artery. Easy.
