Where does the belly button lead to? Answered

I know it scars over after birth, but what if you opened it back up? Would it still lead somewhere? Could it be used again as a 'feeding port' if opened?

Sorry for not picking a best answer to my last question about snow. I wasn't convinced there was a best answer but I did learn a lot.


I think a placenta is mostly just an extension (extension cord?) of a fetus's circulatory system, and also the mothers' circulatory system.

If you actually want to connect external plumbing to your veins, there are ways to do this. By the way, if you are disturbed by the sight of needles stuck in people, then you probably should not look at the Wikipedia article for "Intravenous therapy"


Also, if you don't like the sight of blood and gore, then you probably avoid the Wikipedia article for "Placenta"


So, yeah... wow! I'm impressed by the way this innocent topic can excite so many phobias at once, including hemophobia (fear of blood) and trypanophobia (fear of needles)



Implantable ports, total parenteral nutrition, volume expanders, alot of info there and I have just scratched the surface. thanks! I did see about an implantable silcone port and injecting nutrients directly into the heart. It's not the belly button idea but it's close.

here mate heres the answer The navel (clinically known as the umbilicus, colloquially known as the belly button, or tummy button) is a hollowed or sometimes raised area on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel.

Until birth, the umbilicus (where the navel will be) has blood vessels running through it.

Shortly after birth, the blood vessels that lead to the belly button disappear. Their cells are destroyed and the materials re-used. It was a temporary connection.

If you open it back up, you wold be looking at the inside of the abdomen, but it leads nowhere useful.

in an emergency, an "inny" can be used as a USB port, and an "outy" can connect to a cigarette lighter.

Lmfao. Out of the blue, toga dan with the new best answer.

I'm glad it was a useful answer. Leave a footnote if u make an ible about it.

They say a picture is worth a 1000 words.

Without the placenta I don't think it will work after birth.

Straight to the heart and back out into the amniotic fluid. That baby eats blood and breathes amniotic fluid. Think how little feces a baby must produce in 9 months gestation.
Thanks for the picture. Definitely best answer but I don't have the option yet. Thanks rick!

1. In the womb a baby doesn't breathe in the normal sense - Oxygen is provided by the mother.

2. As no solid material is passed over the umbilical no feces are produced.

3 at late stage birth babies may urinate in the womb.

Sorry, no longer best answer. Still a good answer. A link to more info might have kept you as best answer. Next time rick. Next time.

Circulation of materials like your railroad simulation, a better road bed eventually prevails :)

In anyone but an a newborn, nowhere. Its a weakness in the stomach muscles - that's what an umbilical hernia is.

The bellybutton goes nowhere, except in a newborn. The bloodvessels are absorbed by the body. All that is left is slight weakness in the abdominal wall. The weakness can lead to an umbilical hernia.

I see. So the belly button is an anatomical flaw. We'd be better off without them. Interesting. Or is it vestigial? It may serve a purpose. THe appendix was once thought to be useless, as were tonsils.

It SERVED a purpose, it WAS the port.

And no, babies don't eat blood and secrete amniotic fluid.

The baby's circulation is passed into the placenta, the mother's circulation INDEPENDENTLY feeds the placenta - baby gets their nutrients straight from the blood. Much of the cleaning of the blood is done by passing waste BACK to the mother's blood via osmosis and diffusion in the capillaries of the placental interface. Baby's kidneys do function though, and some waste products pass to the amniotic fluid, which is itself cleaned by the mother's system.

Mostly correct. Except that babies do get nutrients from amniotic fluid. That is what they breathe. It is their atmosphere.

The blood passes from the womb of the mother by membrane into the placenta, the mothers blood doesnt feed the baby directly, thank heaven. But her blood purified by the placenta does.

Babies eat blood and they breathe amniotivc fluid and they secrete/urinate amniotic fluid.
