The belly button does not have a biological purpose. It is simply the place where the umbilical cord was once attached. During life in the womb the umbilical cord connects the foetus to its mother's placenta. The placenta delivers oxygen, nutrients, and antibodies to the foetus; it also removes waste products.

HERE IS YOUR ANSWER-

Your belly button marks the spot where your umbilical (say: um-BIL-ih-kul) cord was once attached. This cord is a soft, bendable tube that carried nutrients — vitamins and minerals — from your mother to you, back when you were in her belly (womb). A belly button is also called a navel.
