Quiz: Where is the chicken's belly button?

Whatever your answer is, slowly take it. Want to know if the chicken is navel, see what the navel is.

By definition, the navel is essentially not a separate part. It is a scar on the abdomen, where the fetal abdomen is connected to the placenta. After the baby is born, the placenta will be removed, leaving a dent called the navel.

With this definition, we can say all animals - from bears, rabbits, dogs, cats, pigs . even whales also have navel, because they give birth to babies.

And also logically, animals that lay eggs - ie, without placenta - are naturally without navel, right?

If you think so, unfortunately, you are wrong!

First, look at the picture below. That is the image of chicken embryos while inside the egg.

In fact, the inside of the chicken embryo has a very small wire, connected to the egg yolk to bring nutrients to the embryo to develop. In some ways, this is the umbilical cord of the chicken, ie the umbilical chicken.

When the egg hatches, the cord still leaves a small scar on the chicken belly - the belly button itself. However, this scar is extremely small, and over time it fades away, unable to be observed.

Umbilical cord here this regime.

In short, chickens have navel. It's just that we can't see it in mature chickens.
