bronchopulmonary segment

A discrete anatomical unit of the lung that is composed of a segmental bronchus and the lung tissue supplied by that bronchus. A bronchopulmonary segment exhibits a pyramidal shape, with its apex pointing towards the center of the lung and its base toward the pleural surface. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the bronchopulmonary segment is

A discrete anatomical unit of the lung that is composed of a segmental bronchus and the lung tissue supplied by that bronchus. A bronchopulmonary segment exhibits a pyramidal shape, with its apex pointing towards the center of the lung and its base toward the pleural surface. The atlas records it as a organ at the organ scale in the human body.

Where the bronchopulmonary segment is

It sits in the thorax and trunk, within the respiratory system. 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 bronchopulmonary segment connects to

The atlas records 8 typed relationships for it, across 6 kinds of connection. part of lobe of lung.

Supply and innervation

Venous drainage: segmental pulmonary vein and subsegmental pulmonary vein.

Also called

Also recorded as lung segment. Searching any of those names reaches this page.

Questions

Where is the bronchopulmonary segment?

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

What does the bronchopulmonary segment connect to?

Part of: lobe of lung.

Is the bronchopulmonary segment 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.
