PATHOLOGY

Detailed explanation-1: -The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.

Detailed explanation-2: -Pulmonary veins are the vessels which carry oxygenated blood from the lungs to the heart of the human body. There is a pair of pulmonary veins which carry oxygenated blood from left and right its lungs to the left atrium of the heart.

Detailed explanation-3: -Pulmonary arteries carry deoxygenated blood from the heart to the lungs. This is unlike other arteries which carry oxygenated blood. Similarly, oxygenated blood is carried by the pulmonary vein unlike other veins.
