Umbilical-Mesenteric Artery

The umbilical mesenteric artery (A. omphalic, a. omphalo-mesenterica).

One of the terminal branches of the abdominal aorta (celiac trunk aorta) accompanies the mesentery of the small intestine and flows into it near the exit from the intestinal loop of the ileum; after its mouth it bifurcates according to the direction of the branches. Having entered the mesenteries between the descending colon and the greater omentum, the umbilical artery connects with its branches: - drainage to the liver - inferior vena cava and left gastric arteries (in the fetus) - to the intestines - digestive tract with the ileocecocolic artery These branches would be important for human life, but in the adult body they serve rather to support regeneration. If the left gastric branch is damaged, infection or other source of bleeding in the abdomen will quickly lead to death. The only right gastric arterial branch is important for cardiac function. The umbilical arteries play an important role in supplying the ovaries and their derivatives in the female body, especially during egg development (for which the umbilical vessels are necessary to access the maternal blood supply. In infancy, the right umbilical arterya can be bilateral and serves as a source of higher demands under stress conditions on digestion. Both the umbilical time of human pregnancy and the umbilical blood flow in the fetus are predominantly taken from the pulmonary plexus. This is due to the fact that due to the development of the lungs, the child develops the need for feeders such as arteries. The two right umbilical arteriess in early formation are sometimes reunited and connected within their common channel. This leads to the appearance of small defects in the vessels and the inner lining, which remain ultimately without any known consequences. In contrast, the left umbilical artery - link - s usually remains individual, branches along the borders of the bodies of both legs of the spine and has very little communication with the main blood stream.
