A pulmonary vein is a ample blood vessel of the circulatory system that carries blood from the lungs to the larboard atrium of the heart. In bodies there are four pulmonary veins, two from anniversary lung. They backpack oxygenated blood, which is abnormal aback about all added veins backpack deoxygenated blood.

Types
They are four in number, two from anniversary lung, and are bankrupt of valves. They are
- right inferior
- right superior
- left inferior
- left superior
Path
They arise in a capillary net-work aloft the walls of the air sacs, area they are connected with the capillary ramifications of the pulmonary artery, and, abutting together, anatomy one barge for anniversary lobule.
These argosy chain successively, anatomy a individual block for anniversary lobe, three for the right, and two for the larboard lung.
The attitude from the average affiliate of the appropriate lung about unites that from the high lobe, so that ultimately two trunks from anniversary lung are formed; they bore the coarse band of the pericardium and accessible alone into the high and aback allotment of the left atrium.
Occasionally the three veins on the appropriate ancillary abide separate, and not infrequently the two larboard pulmonary veins end by a accepted aperture into the larboard atrium. Therefore, the amount of pulmonary veins aperture into the larboard atrium can alter amid three and 5 in the advantageous population.
At the basis of the lung, the aloft pulmonary attitude lies in foreground of and a little beneath the pulmonary artery; the inferior is anchored at the everyman allotment of the hilus of the lung and on a even after to the high vein. Abaft the pulmonary avenue is the bronchus.
Within the pericardium, their antecedent surfaces are invested by the aqueous band of this membrane.
The appropriate pulmonary veins canyon abaft the right atrium and superior vena cava; the larboard in foreground of the bottomward thoracic aorta.
