Given the likely typographical error, the intended question is likely "What is Navel?" A navel, also commonly known as a belly button, is a scar on the abdomen caused by the umbilical cord's removal after birth.
Here's a breakdown:
-
Definition: The navel is a depression in the middle of the abdomen.
-
Origin: It marks the point where the umbilical cord was formerly attached, connecting the embryo/fetus to the mother during gestation. The umbilical cord provides the developing baby with nutrients and oxygen.
-
Another name: It is also referred to as the umbilicus.
-
Appearance: Navels vary in appearance (innie vs. outie) based on how the umbilical cord stump heals after being cut. This variation is due to scar tissue formation, not the cutting technique.
-
Function: The navel has no physiological function after birth. It is simply a scar.
