The paired aortic arch 4 arteries branch directly from the ventral aorta to the lateral dorsal aorta, and are retained as the branchial arteries providing circulation through the gills in the adult.[AAO] Aortic arches 3 and 4 are not remodeled but are retained largely intact as the branchial arteries providing circulation through the gills. These areches are direct branches from the ventral aorta to the lateral dorsal aorta.
