abdominal aorta in dogs

Abdominal part of aorta: the distal part of the descending aorta, which is the continuation of the thoracic part and gives rise to the inferior phrenic, lumbar, median sacral, superior and inferior mesenteric, middle suprarenal, renal, and testicular or ovarian arteries, and celiac trunk[BTO]. The abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of descending aorta(of the thorax). [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the abdominal aorta is

Abdominal part of aorta: the distal part of the descending aorta, which is the continuation of the thoracic part and gives rise to the inferior phrenic, lumbar, median sacral, superior and inferior mesenteric, middle suprarenal, renal, and testicular or ovarian arteries, and celiac trunk[BTO]. The abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of descending aorta(of the thorax). [WP,unvetted]. The atlas records it as a organ at the organ scale in the dog.

Where the abdominal aorta is

It sits 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 abdominal aorta connects to

The atlas records 15 typed relationships for it, across 7 kinds of connection. part of aorta, descending aorta and organ.

Supply and innervation

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

Questions

Where is the abdominal aorta?

It sits 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 does the abdominal aorta connect to?

Part of: aorta, descending aorta and organ.

Is the abdominal 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.
