Vein Pulmonary Upper Right

The pulmonary vein superior right (lat. v. pulmonalis superior dextra) is one of the two superior pulmonary veins draining the upper lobe of the right lung.

The vein originates from the confluence of the venous vessels of the upper lobe of the right lung. It then passes back along the anterior surface of the upper lobe bronchus and flows into the atriosuperficial sinus of the right atrium. The diameter of the vein is 15-20 mm.

Together with the inferior pulmonary vein of the right lung and two pulmonary veins of the left lung, the right superior pulmonary vein forms the pulmonary veins, through which venous blood from the lungs enters the left atrium.

Thus, the right superior pulmonary vein plays an important role in returning arterial blood from the lungs to the systemic circulation.

The article below describes the right pulmonary superior vein:

The right pulmonary vein is a venous vessel that drains into the right atrium. The right inferior vena cava divides into the right and left hepatic veins and the superior and inferior vena cava. The superior vena cava (right syst.) is a continuation of the common iliac vein (left syst.). The lateral part of the right superior vena cava at the level of the third intercostal space passes into the azygos and semi-gypsy veins. Before entering the right atrium, the superior vena cava forms the ascending superior vena cava (tributaries: azygos, semi-gypsy vein, right ovarian vein
