pulmonary alveolar duct in dogs

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 dog.

Where the pulmonary alveolar duct is

It sits in the thorax and trunk, within the respiratory system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the pulmonary alveolar duct connects to

The atlas records 8 typed relationships for it, across 4 kinds of connection. part of alveolar system, lung and respiratory airway, and 1 more.

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. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What does the pulmonary alveolar duct connect to?

Part of: alveolar system, lung, respiratory airway and respiratory system.

Is the pulmonary alveolar duct the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
