Artery Umbilical

**Umbilical artery** – one of the arteries coming from the abdominal part of the aorta; supplies blood to the fetus during intrauterine life. A.umbilicaliss.pna.aetodiaphragmatis. Located inside the umbilical cord and near the stomach of the embryo. Before entering the placental cavity, it protrudes into the abdominal cavity of the fetus, forming a terminal loop. It is formed from the bifurcation of the aoa near the xiphoid process and is directed upward and forward; then it crosses the anterior surface of the liver in a curved manner, located on the right side of the umbilical vein, bends around the stomach in front and enters the abdominal wall of the fetus from top to bottom from back to front from the side. The artery is thinner and longer compared to the umbilical artery running inside the placenta. At the site of attachment of the placenta, it passes through the thickness of the umbilical membranes and is divided into paired branches, giving direction to the vessels of the umbilical end of the placenta, directly to the umbilical veins, umbilical duct and chorionic plate. The terminal branch of the artery, forming anastomoses with the branches of the iliac artery at the point of its continuation in the fetal trunk and face through the remains of the yolk sac, at the exit into the hernial sac of the vessel is the first branch of the umbilical-mesenteric branch of the vagus intestine to the cecum. When the umbilical cord is 4 cm in diameter, the length of the primacy of this artery is about 16 cm, its diameter is about 2 mm.
