why do belly buttons remain after birth?

Question

do they serve any purpose after delivery, where are they attached internally?

Answer 1

I'm no scientist, but the belly button is a bit more than just a scar. The baby's body has to reroute it's interior plumbing, and this is a "dead end" that has been closed off. (The baby now breathes air and gets oxygen through the lungs, and gets it's nutrition through drinking milk.) The umbilical cord was the major artery (coming in) and vein (going out for waste.) The closed off former cord heals quite remarkably. Occasionally the stomach muscles will not knit together in this area, causing an umbilical hernia. I had this condition, and had to have it surgically repaired when I was 4.

A much more philosophical question is to ask, did Adam and Eve have belly buttons? ;-)

Answer 2

Why do I have a belly button?

A belly button, sometimes called a navel, is something everyone in the world has! From Alaska to Zimbabwe - and every place in between - people have belly buttons. And they're always in the same place on their bodies.

As a baby develops inside the mother, he or she floats in fluid inside the mother's womb. While the baby is in there, he or she can't breathe air or eat food. That's where the umbilical cord comes in. The umbilical cord is a flexible tube that carries oxygen and nutrients from the mother to the baby. It also carries wastes away from the baby back to the mother, so she can get rid of them. Your belly button marks the spot where your umbilical cord was once attached.

When the baby is born, he or she lets out a cry. This lets everyone know that the baby can breathe on his or her own. The baby will also soon be drinking milk and getting rid of wastes on his or her own - as anybody who has seen a dirty diaper will tell you!

The brand-new baby doesn't need an umbilical cord anymore. The doctor cuts the umbilical cord and a tiny stump is left. When this stump falls off after a few weeks, the baby is left with his or her very own baby belly button. It might be an innie or an outtie - which kind do you have?

Answer 3

It is the connection between baby(inside womb) and mother 's uterus wall. through the baby gets food for its development and growth
After delivery it does not serve any purpose .Because baby gets food in the form of blood from mom, the um;bell cal card or belly button had lot of blood vessels

Answer 4

It is there to make you look scary back in the cavemen days. A prey/predator will look at man and see the 2 nipples and belly button. The 2 nipples will look like eyes and the belly button will look like the mouth. So they see a big face. (<☺> .. <☺>)

Answer 5

It's just a scar after the umbilical cord falls off.

Answer 6

it is a scar tissue that represents attatchment of umbilical cord on the fetus. they dont serve any purpose after delivery and internally it is oliterated after birth

Answer 7

That is such a good question! And an interesting one!

Sorry I don't have the answer but I'll be looking for others to answer it who may know.

Good job!

Answer 8

so we can breathe oxygen through them. we need them when under water, also it functions as a body sensor.

yea, its a scar, for when that weird ugly tube comes off after birth and goes in to your tummy.

Answer 9

there is no purpose for "the button". the button is just a result of cutting the cord. the cord connects the child to the mother during pregnancy. the blood vessels in the cord are used to transport nutrients and oxygen and not "food" that the mother eats in the typical sense.

Answer 10
