lobar bronchus in dogs
The lobar bronchus is the major airway within the respiratory tree that starts by division of the principal bronchi on both sides and ends at the point of its own subdivision into tertiary or segmental bronchi[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the lobar bronchus is
The lobar bronchus is the major airway within the respiratory tree that starts by division of the principal bronchi on both sides and ends at the point of its own subdivision into tertiary or segmental bronchi[GO]. The atlas records it as a organ at the organ scale in the dog.
Where the lobar bronchus is
It sits in the thorax and trunk, within the respiratory system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.
What the lobar bronchus connects to
The atlas records 9 typed relationships for it, across 4 kinds of connection. part of lobe of lung and lung.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the lobar bronchus. 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 bronchi lobaris, secondary bronchus, lobar bronchi and secondary bronchi. Searching any of those names reaches this page.

Is the lobar bronchus 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.
