what is naval in body

The naval, or belly button, is a small depression in the abdominal wall at the point of detachment of the umbilical cord after birth. The umbilical cord is a soft, bendable tube that carried nutrients from the mother to the developing fetus. After birth, the belly button becomes a scar or remnant of the umbilical cord and has no function. In some cultures, such as Arabic-Levantine culture, the belly button is considered an important part of the body and is the focus of dance movements. Additionally, the Japanese have long had a special regard for the navel, as it was believed to symbolize the center where life began. Finally, belly button lint is a common phenomenon that occurs when stomach hair scratches off tiny t-shirt fibers and directs them towards the belly button.
