intra-acinar arteriole
An arteriole that branches from the pulmonary arteriole and supplies deoxygenated blood to the pulmonary capillaries in the alveoli of the lungs. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the intra-acinar arteriole is
An arteriole that branches from the pulmonary arteriole and supplies deoxygenated blood to the pulmonary capillaries in the alveoli of the lungs. The atlas records it as a organ at the organ scale in the human body.
Where the intra-acinar arteriole 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 arteriole connects to
The atlas records 11 typed relationships for it, across 3 kinds of connection. part of artery, cardiovascular system and lung, and 5 more.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the intra-acinar arteriole. 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 arteriole?
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 does the intra-acinar arteriole connect to?
Part of: artery, cardiovascular system, lung, pulmonary acinus, respiratory system and thoracic segment of trunk, and 2 more.
Is the intra-acinar arteriole 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.
