Pulmonary Vein Alveolar
Venae pulmonales is the Latin pronunciation for Pulmonary Vein. Pulmonary vein is a large blood vessel that drains the oxygenated blood to the Left Atrium of Heart after receiving it from Lungs.

Pulmonary Vein Alveolar
There are total four Pulmonary Veins, Two from each lung. It is among those few veins that carry oxygenated blood (veins usually carry deoxygenated blood) . Two Pulmonary Veins arise out of each Lung Hilum (Cardiac Impression on Lung). These veins receive blood from three-four Bronchial Veins and eventually drain into the Left Atrium of Heart. Veins are fixed to Pericardium (doubled wall sac containing the heart and large vessels) and the Pulmonary Arteries travel alongside these Pulmonary Veins. Right superior Pulmonary Vein lies in front of the Pulmonary Artery at the base of the Lung. The Inferior Pulmonary Vein is located at lowest part of Lung Hilum. The Right Pulmonary Veins which carry the oxygenated blood pass back the Right Atrium and Superior Vena Cava. The left Pulmonary Veins lie in front of Thoracic Aorta. In healthy population there is a variation in the number of Pulmonary Veins opening in the Left Atrium from three to four.
Pulmonary Veins play a key role in Respiration by carrying oxygenated blood from the Alveolus (little Cavity) to the heart.
Pulmonary Veins can suffer from a disease known as Pulmonary Vein Stenosis. It is a rare condition causing narrowing of pulmonary veins.
