What's an Umbilical Cord?

Umbilical Cord

Say: um-BIL-ih-kul kord

This is the name for the long tube that runs between a mother and her unborn baby. It carries oxygen and nutrients to the baby and waste away from the baby. When the baby is born, the doctor cuts the umbilical cord and a small piece is left attached to the baby. When this piece falls off, you can see the baby's belly button!
