The umbilical cord connects a baby in the womb to its mother. It runs from an opening in your babyâs stomach to the placenta in the womb. The average cord is about 50cm (20 inches) long. The umbilical cord carries oxygen and nutrients from the placenta into your babyâs bloodstream.
The umbilical cord develops from and contains remnants of the yolk sac and allantois (and is therefore derived from the zygote). It forms by the fifth week of fetal development, replacing the yolk sac as the source of nutrients for the fetus.he umbilical cord develops from and contains remnants of the yolk sac and allantois (and is therefore derived from the zygote).
