respiratory bronchiole in dogs

A bronchiole that is the first segment of the respiratory zone. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the respiratory bronchiole is

A bronchiole that is the first segment of the respiratory zone. The atlas records it as a organ at the organ scale in the dog.

Where the respiratory bronchiole is

It sits in the thorax and trunk, within the respiratory system. Positioned deliberately as part of this species body plan.

What the respiratory bronchiole connects to

The atlas records 9 typed relationships for it, across 7 kinds of connection. part of pulmonary acinus.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the respiratory bronchiole. 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 bronchiolus respiratorii and bronchiolus respiratorius. Searching any of those names reaches this page.

Questions

Where is the respiratory bronchiole?
