An astonishing switch happens in the apportionment with the two arteries constricting to stop the flow of blood to the placenta and then the vein slowly collapsing.
Internally the veins and arteries in the string close upwards and form ligaments, which are tough connective tissues.
These ligaments split up up the liver into sections and remain fastened to the within of the bellybutton.
The function of the umbilical arteries closest to the belly button degenerates into ligaments that serve no real purpose but the more internal part becomes part of the circulatory system and is establish in the pelvis supplying claret to parts of the bladder, ureters and ductus deferens (a tube sperm moves through in males).
