Is the navel connected to the umbilical cord at birth.
Yes, the navel, or belly button, is the remnant of the umbilical cord that connected a developing fetus to the placenta during pregnancy. The umbilical cord provides nutrients and oxygen to the fetus and removes waste products. At birth, the umbilical cord is cut, and the remaining stump eventually falls off, leaving the navel as a permanent mark on the abdomen.
