A belly button normally called a navel is part of a human body, it marks the outie spot where your umbilical cord is attached. The umbilical cord is a flexible tube that carries oxygen and nutrients from the mother to the baby and is the innie of the belly. It also carries wastes away from the baby back to the mother, so she can get rid of them.
Once the baby is born then the umbilical cord is cut by the doctor and a tiny stump is left, which drops off after few weeks and that turns out to be the navel or belly button. Many don’t believe that the belly button is due to the umbilical cord being cut. Therefore, what’s the theory behind the innie and outie of a belly button?
Innie belly button goes inwards, where your umbilical cord is connected and was your lifeline when you were in your mother’s womb. Most people end up with an innie belly button.
An outie usually occurs when more of the umbilical cord is left when it’s cut, leading to more skin left over once it dries out. In some rare cases, an outie is caused by a condition known as an umbilical hernia.
An umbilical hernia usually doesn’t hurt, but if the cord area doesn’t close on its own before a child is 3 or 4, it might require surgery.
The umbilical cord was your lifeline when you were inside your mother’s womb, a rope-like cord with blood vessels that provided nutrients and oxygen. And it is cut instantly after the baby is born, which slowly dries and falls off on its own.
The theory of one getting the belly button was solely on how the doctor had cut the umbilical cord, is totally wrong and misunderstood.
After a baby is born, the umbilical cord is no longer needed and the body has a natural way of getting rid of the cord. On its own, the body closes up the point where the umbilical cord joined the body and formed the belly button.
