external iliac vein

A large vein that connects the femoral vein to the common iliac vein. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins). Both external iliac veins are accompanied along their course by external iliac arteries. [WP,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

Where is the external iliac vein?

It sits within the cardiovascular system. Positioned deliberately as part of this species body plan.

What does the external iliac vein connect to?

A kind of: vein.

Is the external iliac 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.
