alveolus of lung in dogs

Spherical outcropping of the respiratory bronchioles and primary site of gas exchange with the blood. Alveoli are particular to mammalian lungs. Different structures are involved in gas exchange in other vertebrates[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the alveolus of lung is

Spherical outcropping of the respiratory bronchioles and primary site of gas exchange with the blood. Alveoli are particular to mammalian lungs. Different structures are involved in gas exchange in other vertebrates[WP]. The atlas records it as a organ at the organ scale in the dog.

Where the alveolus of lung is

It sits in the thorax and trunk, within the respiratory system. Positioned deliberately as part of this species body plan.

What the alveolus of lung connects to

The atlas records 21 typed relationships for it, across 8 kinds of connection. part of alveolar system, lung and organ, and 2 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the alveolus of lung. 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 alveolus, alveolus pulmonis, lung alveolus, pulmonary alveolus, respiratory alveolus and alveoli, and 1 more. Searching any of those names reaches this page.

Questions

Where is the alveolus of lung?

It sits in the thorax and trunk, within the respiratory system. Positioned deliberately as part of this species body plan.

What does the alveolus of lung connect to?

Part of: alveolar system, lung, organ, pulmonary acinus and alveolar sac.

Is the alveolus of lung the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
