The term "belly button" is a colloquial name for the navel, which is the scar left behind after the umbilical cord is cut and detached from a newborn baby's abdomen shortly after birth. The scientific term for the belly button is the "umbilicus."
During pregnancy, the umbilical cord serves as the lifeline between the developing fetus and the mother. It supplies essential nutrients and oxygen from the mother's placenta to the baby, as well as removes waste products. Once the baby is born, the umbilical cord is clamped and cut, leaving a small stump on the baby's abdomen.
In the days following birth, the stump gradually dries up and falls off, leaving a small depression or scar on the baby's belly. This scar is what we commonly refer to as the "belly button" or "navel." Its shape often resembles a small indentation, similar to the appearance of a button.
The term "belly button" is likely derived from the fact that the navel is located on the belly, which is the front part of the torso. Its association with a "button" may be due to its small and round appearance, reminiscent of a button on clothing.
The navel or belly button has no physiological function after birth and is considered a vestigial structure, meaning it is a remnant of a structure that served a purpose in the past but is no longer necessary for the organism's survival. While it may not have any biological significance, the belly button has cultural and symbolic importance in various societies and is sometimes regarded as a unique and personal feature on an individual's body.
