pulmonary alveolar duct
The respiratory conducting tubes distal to the respiratory bronchiole that lead to the alveolar sacs and the alveoli. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the pulmonary alveolar duct is
The respiratory conducting tubes distal to the respiratory bronchiole that lead to the alveolar sacs and the alveoli. The atlas records it as a organ at the organ scale in the human body.
Where the pulmonary alveolar duct is
It sits in the thorax and trunk, within the respiratory system. 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 pulmonary alveolar duct connects to
The atlas records 3 typed relationships for it, across 2 kinds of connection. part of lung.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the pulmonary alveolar duct. 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.
Also called
Also recorded as alveolar duct, ductus alveolaris and respiratory alveolar duct. Searching any of those names reaches this page.

Questions
Where is the pulmonary alveolar duct?
It sits in the thorax and trunk, within the respiratory system. 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 pulmonary alveolar duct connect to?
Part of: lung.
Is the pulmonary alveolar duct 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.
