Synonym: umbilical artery
English:
Definition[Bearbeiten]
The umbilical artery is a paired vascular branch of the internal iliac artery that plays a major role in the foetal circulation and transports foetal blood to the placenta in the umbilical cord.
Background[Bearbeiten]
After birth, the vessel remains only proximally patency (pars patens) and gives off the superior vesical artery and, in men, the deferent duct artery. The distal, larger section (pars occlusa) obliterates to form the medial umbilical ligament, which is visible on the abdominal wall as the medial umbilical plica.
