trachea

The trachea is the portion of the airway that attaches to the bronchi as it branches [GO:dph]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the trachea is

The trachea is the portion of the airway that attaches to the bronchi as it branches [GO:dph]. The atlas records it as a organ at the organ scale in the human body.

Where the trachea is

It sits within the respiratory system. Positioned deliberately as part of this species body plan.

What the trachea connects to

The atlas records 23 typed relationships for it, across 9 kinds of connection. part of tracheobronchial tree.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the trachea. 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 cartilaginous trachea, vertebrate trachea, windpipe and tracheal tubule. Searching any of those names reaches this page.

Questions

Where is the trachea?

It sits within the respiratory system. Positioned deliberately as part of this species body plan.

What does the trachea connect to?

Part of: tracheobronchial tree.

Is the trachea 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.
