Directly behind the navel is a thick fibrous cord formed from the umbilical cord, called the urachus, which originates from the bladder. However, the region around or behind the belly button is referred to as the umbilical region, which contains parts of the stomach, small and large intestine, and the pancreas. Therefore, there are no organs behind the belly button, but there is a fibrous cord called the urachus that originates from the bladder.
