Detailed explanation-1: -Your pulmonary veins are the only veins in your body that carry oxygen-rich blood. All your other veins carry oxygen-poor blood. Similarly, your pulmonary arteries are the only arteries that carry oxygen-poor blood. All the rest of your arteries carry oxygen-rich blood.

Detailed explanation-2: -The lung veins sometimes referred to as the pulmonary veins, are blood vessels that transfer freshly oxygenated blood from the lungs to the left atria of the heart.

Detailed explanation-3: -The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

Detailed explanation-4: -While veins usually carry deoxygenated blood from tissues back to the heart, in this case, pulmonary veins are among the few veins that carry oxygenated blood instead. Oxygenated blood from the lungs is circulated back to the heart through the pulmonary veins that drain into the left atrium.

Detailed explanation-5: -Your main pulmonary artery and your aorta are the two great vessels that carry blood out of your heart. A crucial difference is that your pulmonary artery carries oxygen-poor (deoxygenated) blood, while your aorta carries oxygen-rich (oxygenated) blood.
