dorsal aorta in dogs
The dorsal aorta is a blood vessel in a single-pass circulatory system that carries oxygenated blood from the gills to the rest of the body. In a single-pass circulatory system blood passes once through the heart to supply the body once. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the dorsal aorta is
The dorsal aorta is a blood vessel in a single-pass circulatory system that carries oxygenated blood from the gills to the rest of the body. In a single-pass circulatory system blood passes once through the heart to supply the body once. The atlas records it as a organ at the organ scale in the dog.
Where the dorsal aorta is
It sits in the trunk, within the cardiovascular 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 dorsal aorta connects to
The atlas records 14 typed relationships for it, across 6 kinds of connection. part of vasculature of trunk and pair of dorsal aortae.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the dorsal 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
