terminal bronchiole in dogs

A bronchiole that is part of a secondary pulmonary lobule and the last conducting structure of a non-respiratory bronchiole; after this point, the airways have alveoli in their walls. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the terminal bronchiole is

A bronchiole that is part of a secondary pulmonary lobule and the last conducting structure of a non-respiratory bronchiole; after this point, the airways have alveoli in their walls. The atlas records it as a organ at the organ scale in the dog.

Where the terminal bronchiole is

It sits in the thorax and trunk, within the respiratory system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the terminal bronchiole connects to

The atlas records 10 typed relationships for it, across 5 kinds of connection. part of lobe of lung, lung and lung parenchyma, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the terminal 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 terminalis, bronchioli terminalis and terminal bronchiole tube. Searching any of those names reaches this page.

Questions

Where is the terminal bronchiole?

It sits in the thorax and trunk, within the respiratory system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the terminal bronchiole connect to?

Part of: lobe of lung, lung, lung parenchyma and organ.

Is the terminal bronchiole 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.
