vitelline vein

The paired veins that carry blood from the yolk sac back to the embryo. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the vitelline vein is

The paired veins that carry blood from the yolk sac back to the embryo. The atlas records it as a vein at the organ scale in the human body.

Where the vitelline vein is

It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.

What the vitelline vein connects to

The atlas records 8 typed relationships for it, across 5 kinds of connection. part of systemic venous system and vasculature.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the vitelline vein. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as embryonic vitelline vein, vascular vitelline network, vena vitellina, omphalomesenteric vein, vein of omphalomesenteric system and vitelline veins. Searching any of those names reaches this page.

Questions

Where is the vitelline vein?

It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.

What does the vitelline vein connect to?

Part of: systemic venous system and vasculature.

Is the vitelline vein the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
