Pulmonary vein

The four pulmonary veins on the human heart (shown in brown).

The pulmonary vein, or pulmonary vein, is a large blood vessel (vein). In humans there are normally two pulmonary veins (pulmonary veins) from the left and right lungs. They open into the left atrium . The pulmonary veins are part of the pulmonary circulation (small circulation) and, together with their branches, belong to the pulmonary arteries ( Arteriae pulmonales ) to the vasa publica of the lungs. The pulmonary veins carry oxygen-rich blood, which in the course of pulmonary respiration in the capillaries of the alveoli (alveoli) with oxygen enriched, back to the heart.

Obstruction of the outflow from the pulmonary veins can lead to an increase in pressure in the pulmonary circulation and thus to pulmonary hypertension .
