what is a navel

A navel, also known as a belly button, is a protruding, flat, or hollowed area on the abdomen at the attachment site of the umbilical cord. It is a scar left by the detachment of the umbilical cord, which is a flexible tube that carries nutrients from a mother to a baby while the baby is still in the mother's womb. When a baby is born, the doctor cuts the cord and a small piece is left attached to the baby. When this piece falls off, the baby gets a belly button, or navel. The navel is unique to each individual and can take various forms, such as an "innie" or an "outie" based on the appearance of the umbilical tip. It is a common site of incision for various surgeries, and it has cultural significance in some societies, such as in Japanese and Arabic-Levantine cultures
