intra-acinar venule

A venule that receives drainage from the capillary beds after blood has perfused the pulmonary alveoli, and is tributary of the pulmonary venules.

Frequently Asked Questions

What is the intra-acinar venule?
The intra-acinar venule is a small venous vessel that receives blood after it has perfused the pulmonary alveoli through the capillary beds, and serves as a tributary of the pulmonary venules.
Where is the intra-acinar venule located?
Intra-acinar venules are located within the lung acinus, situated at the periphery of the alveolar capillary network, collecting oxygenated blood after gas exchange has taken place.
What is the function of the intra-acinar venule?
The intra-acinar venule is involved in collecting freshly oxygenated blood from the alveolar capillary beds and channeling it toward the pulmonary venules for return to the left atrium.
What conditions may be associated with the intra-acinar venule?
Pulmonary veno-occlusive disease, pulmonary edema, interstitial lung diseases, or conditions causing pulmonary venous hypertension may be associated with changes affecting intra-acinar venules.
How is the intra-acinar venule examined?
Intra-acinar venules may be assessed through pulmonary biopsy with histological and immunohistochemical analysis, CT of the lungs with vascular evaluation, or right heart catheterization measuring wedge pressure as a surrogate for pulmonary venous pressure.
