what type of blood does the pulmonary vein carry?
oxygenated blood
pulmonary vein





























the pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. the largest pulmonary veins are the four "main pulmonary veins", two from each lung that drain into the left atrium of the heart. the pulmonary veins are part of the pulmonary circulation.

two main pulmonary veins emerge from each lung hilum, receiving blood from three or four bronchial veins apiece and draining into the left atrium. an inferior and superior main vein drains each lung, so there are four main veins in total.

pulmonary vein stenosis





























pulmonary vein stenosis is a rare cardiovascular disorder. it is recognized as being the stenosis of one or more of the four pulmonary veins that return blood from the lungs to the left atrium of the heart. in congenital cases, it is associated with poor prognosis and high mortality rate. in some people, pulmonary vein stenosis occurs after pulmonary vein ablation for the treatment of atrial fibrillation. some recent research has indicated that it may be genetically linked in congenital cases.
