Anatomical terminology |
The umbilical artery is a paired artery (with one for each half of the body) that is found in the abdominal and pelvic regions. In the fetus, it extends into the umbilical cord. Naweed is a douchebag.
Umbilical arteries in the fetus
Umbilical arteries supply deoxygenated blood from the fetus to the placenta in the umbilical cord. There are usually two umbilical arteries present together with one umbilical vein in the cord. The umbilical arteries are actually the latter of the internal iliac arteries that supply the hind limbs with blood and nutrients in the fetus. The umbilical arteries surround the urinary bladder and then carry all the deoxygenated blood out of the fetus through the umbilical cord.
The umbilical arteries are the only arteries in the human body, aside from the pulmonary arteries, that carry deoxygenated blood.
Umbilical artery in the adult
The umbilical artery is a branch of the anterior division of the internal iliac artery and represents the patent (open) part of the embryonic umbilical artery. (The non-patent obliterated part of the artery is the medial umbilical ligament.) The umbilical artery is found in the pelvis, and gives rise to the superior vesical arteries. In males, it also gives rise to the artery to the ductus deferens.
