Umbilical artery artery to the ductus deferens which can be supplied by the inferior vesical artery in some individuals. Umbilical artery 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. The umbilical arteries supply deoxygenated blood from the fetus to the placenta. Although this blood is typically referred to as deoxygenated, it is important to note that this blood is fetal systemic arterial blood and will have the same amount of oxygen and nutrients as blood distributed to
Medial umbilical ligament Medial umbilical ligament The medial umbilical ligament (or cord of umbilical artery) is a paired structure found in human anatomy. It is on the deep surface of the anterior abdominal wall, and is covered by the medial umbilical folds ("plicae umbilicales mediales"). It should not be confused with the median umbilical ligament, a different structure that represents the remnant of the embryonic urachus. It represents the remnant of the fetal umbilical arteries, which serves no purpose in humans after birth, except for the initial part that becomes the adult superior vesical artery. It may be used as a landmark for
