Does The Umbilical Cord go back In?

After a baby is born does the umbilical cord go back inside the womens body aafter it is cut>(like a Tape measurer) or what does it all come out with the placenta? so no two babies of a womans are nourished by the same umbilical cord?

1. It comes out with the placenta.
2. IT COMES OUT WITH THE PLACENTA
3. It comes out with the placenta, but the tape measure picture gave me a big laugh! It reminded me of my second child who surprised the doctor by showing up a little faster than she expected. She caught her, but joked -- "don't worry, that's why they're on bungie cords." ;-)
4. This is a good question, and your analogy is really funny. The umbilical cord does in fact come out with the placenta. A new placenta and cord are grown for each baby. In early pregnancy, the baby is nourished by the "yolk sac" until the placenta and umbilical cord are finished developing. "The umbilical cord develops from the same sperm and ovum from which the placenta and fetus develop, and contains remnants of the yolk sac and allantois. It forms by the fifth week of fetal development, replacing the yolk sac as the source of nutrients for the fetus.[1] In humans, the umbilical cord in a full term neonate is usually about 50 centimetres (19.7 in) long and about 2 centimetres (0.75 in) diameter, shrinking rapidly in diameter in the after birth. In the third stage of labour, after the child is born, the uterus spontaneously expels the neonate's placenta along with the cord from the mother's body, 10–45 minutes after the birth. However, the umbilical cord is generally clamped during or within minutes of birth and severed shortly after, a practice of "active management of labor" which has become increasingly controversial due to the lower transfer of placental blood to the neonate and associated stressors. The health benefits of non-clamping of the cord and delayed umbilical severance are receiving attention in medical journals.[2][3][4] Today there are umbilical cord clamps which combine the cord clamps with the knife. These clamps are safer and faster, allowing one to first apply the cord clamp and then cut the umbilical cord. After the cord is clamped and cut (Western obstetrical protocol) the newborn wears a plastic clip on the navel area until the compressed region of the cord has dried and sealed sufficiently. The remaining umbilical stub remains for up to 2–3 weeks as it dries and then falls off. In nonseverance scenarios, also called lotus birth, the umbilical cord is wrapped up to within an inch of the newborn's belly, and the entire intact cord is allowed to dry like a sinew, which then falls off.[5]" http://en.wikipedia.org/wiki/Umbilical_cord
5. It all comes out in what is called the "afterbirth" and no two babies are nourished by the same umbilical cord. It is now possible to have the umbilical cord frozen as the cells can be used in the treatment/cure of some diseases that could develop in the baby's lifetime.
6. It comes out with the placenta.
7. No, the umbilical cord is attached to the placenta which you deliver soon after the baby comes out.
