Questions fréquentes

What is the pulmonary venule?
A pulmonary venule is a small vein that drains oxygenated blood from the pulmonary capillary bed after gas exchange occurs in the alveoli.
Where is the pulmonary venule located?
Pulmonary venules are distributed throughout the lung tissue, accompanying the bronchioles and alveoli where oxygen uptake occurs.
What is the function of the pulmonary venule?
Pulmonary venules collect oxygenated blood from the pulmonary capillary network and transport it toward the pulmonary veins for return to the left atrium of the heart.
What is the pulmonary venule connected to?
Pulmonary venules originate from the pulmonary capillary plexus and merge to form progressively larger pulmonary veins that ultimately drain into the left atrium.
Why is the pulmonary venule clinically important?
Pathology affecting pulmonary venules such as stenosis or thrombosis can impair oxygenated blood return to the heart and lead to pulmonary hypertension or systemic hypoxemia.
