From Wikipedia, the free encyclopedia
The vitelline veins are veins that drain blood from the
yolk sac
[1] and the
gut tube
[2] 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.
Beyond this, they are connected to one another by two
anastomotic branches , one on the dorsal, and the other on the ventral aspect of the
duodenal portion of the
intestine . This is encircled by two
venous rings ; into the middle or dorsal anastomosis the
superior mesenteric vein opens.
The portions of the veins above the upper ring become interrupted by the developing
liver and broken up by it into a plexus of small capillary-like vessels termed
sinusoids .

Sinus venosus
The vitelline veins give rise to:
[4]
The branches conveying the blood to the plexus are named the venae advehentes , and become the branches of the
portal vein . The vessels draining the plexus into the sinus venosus are termed the venae revehentes , and form the future
hepatic veins .
[3] Ultimately the left vena revehens no longer communicates directly with the sinus venosus, but opens into the right vena revehens. The persistent part of the upper venous ring, above the opening of the superior mesenteric vein, forms the trunk of the
portal vein .
Function
The vitelline veins drain the
yolk sac during early
embryonic development .
[1]
[5] They also drain the
gut tube in
embryos once this has formed from the yolk sac.
