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.

external definition

The artery in vertebrate embryos that transports blood from the aortic arches to the trunk and limbs. In adult fish it is a major artery that carries oxygenated blood from the efferent branchial arteries to branches that supply the body organ. In adult tetrapods it arises from the systemic arch, Principal unpaired, median artery of the trunk, leading from the paired roots (radices) of the dorsal aorta to the caudal artery. Kimmel et al, 1995.[TAO], Each primitive aorta receives anteriorly a vein 'the vitelline vein' from the yolk-sac, and is prolonged backward on the lateral aspect of the notochord under the name of the dorsal aorta. The dorsal aortae give branches to the yolk-sac, and are continued backward through the body-stalk as the umbilical arteries to the villi of the chorion. The two dorsal aortae combine to become the descending aorta in later development[WP].

homology notes

When vertebrates first appeared, they must have possessed a ventral and dorsal aorta with aortic arches between them.[well established][VHOG]
