Homonym: Navel (Belly)
The navel, commonly known as the belly button, is a small, central scar on the abdomen. It is the remnant of the umbilical cord, which connects a developing fetus to its mother during pregnancy. After birth, the umbilical cord is cut, leaving behind the navel as a permanent mark.
The navel can vary in shape and size among individuals, and it serves no significant biological function in adults. It is often considered a cosmetic feature and can be a focal point in fashion and body art, such as piercings. The navel is also associated with various cultural beliefs and practices.
