What is the umbilical made from?

The umbilical cord is made from three vessels: two arteries and one vein. The arteries carry deoxygenated blood from the fetus to the placenta, while the vein carries oxygenated blood and nutrients from the placenta to the fetus. The umbilical cord is also surrounded by a layer of jelly-like substance called Wharton's jelly, which helps to protect the blood vessels.
