thoracic aorta in dogs

The part of the aorta that extends from the origin at the heart to the diaphragm, and from which arises numerous branches that supply oxygenated blood to the chest cage and the organs within the chest. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the thoracic aorta is

The part of the aorta that extends from the origin at the heart to the diaphragm, and from which arises numerous branches that supply oxygenated blood to the chest cage and the organs within the chest. The atlas records it as a organ at the organ scale in the dog.

Where the thoracic aorta is

It sits in the thorax and trunk, within the cardiovascular 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 thoracic aorta connects to

The atlas records 15 typed relationships for it, across 6 kinds of connection. part of aorta, organ and thoracic segment of trunk.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the thoracic aorta. 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 aorta thoracica, thoracic part of aorta, aorta thoracalis and pars thoracica aortae. Searching any of those names reaches this page.

Questions

Where is the thoracic aorta?

Is the thoracic aorta 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.
