Umbilical cord Umbilical cord In placental mammals, the umbilical cord (also called the navel string, birth cord or funiculus umbilicalis) is a conduit between the developing embryo or fetus and the placenta. During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical arteries) and one vein (the umbilical vein), buried within Wharton's jelly. The umbilical vein supplies the fetus with oxygenated, nutrient-rich blood from the placenta. Conversely, the fetal heart pumps low oxygen containing blood, nutrient-depleted blood through the umbilical arteries back to the placenta. The umbilical cord develops
Umbilical line left portal vein, passing through the patent ductus venosus to the inferior vena cava and right atrium. Appropriate UVC tip position is in the high inferior vena cava to the low right atrium, typically within 1 cm of the diaphragm. If the UVC tip is proximal to ductus venosus it can lead to administration of intravenous fluids into the portal system, with potential portal vein thrombosis, or, in cases of TPN administration, a TPN abscess. Umbilical line An umbilical line is a catheter that is inserted into one of the two arteries or the vein of the umbilical cord. Generally
