Is your navel connected to the urinary system?

The navel, also known as the belly button or umbilicus, is not directly connected to the urinary system. However, during embryonic development, the urachus, a small tubular structure, connects the bladder to the umbilicus. This connection usually closes before birth, leaving a fibrous cord called the median umbilical ligament. Therefore, the navel is no longer directly linked to the urinary system in a fully developed human body.
