pulmonary trunk

An arterial trunk which is continuous with the heart and branches into the pulmonary arteries. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pulmonary trunk is

An arterial trunk which is continuous with the heart and branches into the pulmonary arteries. The atlas records it as a artery at the organ scale in the human body.

Where the pulmonary trunk is

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

What the pulmonary trunk connects to

The atlas records 9 typed relationships for it, across 5 kinds of connection. part of pulmonary vascular system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pulmonary trunk. 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.

Questions

Where is the pulmonary trunk?
