This article is about the embryonic artery. For the artery in adult fish, see Aorta#In other animals.
Dorsal aortae Profile view of a human embryo estimated at twenty or twenty-one days old. (Dorsal aorta labeled at center left.) Latin aortae dorsales Gray's subject #135 506 Carnegie stage 9 Code TE E5.11.2.1.3.0.1 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 aortæ 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.
