| external_definition |
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]. 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] |
