pulmonary arteriole

An arteriole that branches from the pulmonary arteries and supplies deoxygenated blood to the pulmonary capillaries and alveolar capillaries of the lungs. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pulmonary arteriole is

An arteriole that branches from the pulmonary arteries and supplies deoxygenated blood to the pulmonary capillaries and alveolar capillaries of the lungs. The atlas records it as a organ at the organ scale in the human body.

Where the pulmonary arteriole is

It sits in the thorax and trunk, within the cardiovascular and respiratory systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the pulmonary arteriole connects to

The atlas records 8 typed relationships for it, across 3 kinds of connection. part of lung, respiratory system and secondary pulmonary lobule, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pulmonary arteriole. 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 set of all pulmonary arterioles. Searching any of those names reaches this page.

Questions

Where is the pulmonary arteriole?

What does the pulmonary arteriole connect to?

Part of: lung, respiratory system, secondary pulmonary lobule, thoracic segment of trunk and trunk.

Is the pulmonary arteriole 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.
