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. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the intra-acinar venule is

A venule that receives drainage from the capillary beds after blood has perfused the pulmonary alveoli, and is tributary of the pulmonary venules. The atlas records it as a organ at the organ scale in the human body.

Where the intra-acinar venule is

It sits in the thorax and trunk, within the cardiovascular and respiratory systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the intra-acinar venule connects to

The atlas records 10 typed relationships for it, across 3 kinds of connection. part of lung, pulmonary acinus and respiratory system, and 4 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the intra-acinar venule. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Questions

Where is the intra-acinar venule?

What does the intra-acinar venule connect to?

Part of: lung, pulmonary acinus, respiratory system, thoracic segment of trunk, trunk and vascular system, and 1 more.

Is the intra-acinar venule the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
