pulmonary vein
Oxygenated blood conduit
The pulmonary veins carry oxygen-rich blood from the lungs to the heart's left atrium.
Unlike other veins, which carry deoxygenated blood, pulmonary veins transport freshly oxygenated blood—the reverse of the pulmonary arteries, which deliver deoxygenated blood to the lungs.
There are typically four pulmonary veins, two from each lung.
