umbilical artery

https://doi.org/10.1351/goldbook.11338

Paired artery that, in the fetus, returns deoxygenated blood from each half of the fetal body to the placenta, via the umbilical cord.

Note: In the adult, part of the umbilical artery remains open as a branch of the internal iliac artery, and part ceases to be an artery and becomes the medial umbilical ligament.
