Explanation

Pulmonary veins are the ONLY veins in the body that carry oxygenated blood. They transport freshly oxygenated blood from the lungs back to the left atrium of the heart. Arteries normally carry oxygenated blood away from the heart (except for pulmonary arteries), and veins normally carry deoxygenated blood toward the heart. Pulmonary veins are the exceptional case - they're veins that carry 'pure' (oxygenated) blood.
