tracheobronchial tree

The structure from the trachea, bronchi, and bronchioles that forms the airways that supply air to the lungs. The lining of the tracheobronchial tree consists of ciliated columnar epithelial cells. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the tracheobronchial tree is

The structure from the trachea, bronchi, and bronchioles that forms the airways that supply air to the lungs. The lining of the tracheobronchial tree consists of ciliated columnar epithelial cells. The atlas records it as a organ at the organ scale in the human body.

Where the tracheobronchial tree is

It sits within the respiratory system. Only the system is known. The position shown carries almost no spatial information.

What the tracheobronchial tree connects to

The atlas records 11 typed relationships for it, across 4 kinds of connection. part of lower respiratory tract.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the tracheobronchial tree. 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 arbor tracheobronchialis and tracheobronchial system. Searching any of those names reaches this page.

Questions

Where is the tracheobronchial tree?

It sits within the respiratory system. Only the system is known. The position shown carries almost no spatial information.

What does the tracheobronchial tree connect to?

Part of: lower respiratory tract.

Is the tracheobronchial tree 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.
