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
  • 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].
  • 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]
