The vitelline arteries are the arterial counterpart to the
vitelline veins
The vitelline veins are veins that drain blood from the yolk sac and the gut tube during gestation.
Path
They run upward at first in front, and subsequently on either side of the intestinal canal. They unite on the ventral aspect of the canal.

. Like the veins, they play an important role in the
vitelline circulation of blood to and from the
yolk sac
The yolk sac is a membranous sac attached to an embryo, formed by cells of the hypoblast layer of the bilaminar embryonic disc. This is alternatively called the umbilical vesicle by the Terminologia Embryologica (TE), though ''yolk sac'' is ...

dorsal aorta
The dorsal aortae are paired (left and right) embryological vessels which progress to form the descending aorta. The paired dorsal aortae arise from aortic arches that in turn arise from the aortic sac.
The primary dorsal aorta is located deep ...

They give rise to the
celiac artery
The celiac () artery (also spelled ''coeliac''), also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) in ...

superior mesenteric artery
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the du ...

inferior mesenteric artery.
