pulmonary artery

An artery that carries deoxygenated blood from heart to the lungs. They are the only arteries (other than umbilical arteries in the fetus) that carry deoxygenated blood.. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pulmonary artery is

An artery that carries deoxygenated blood from heart to the lungs. They are the only arteries (other than umbilical arteries in the fetus) that carry deoxygenated blood.. The atlas records it as a artery at the organ scale in the human body.

Where the pulmonary artery is

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

What the pulmonary artery connects to

The atlas records 13 typed relationships for it, across 9 kinds of connection. part of pulmonary vascular system.

Supply and innervation

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

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

What does the pulmonary artery connect to?

Part of: pulmonary vascular system.

Is the pulmonary artery 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.
