does a chick breathe while its inside the egg? if yes, how?

Answer 1

Yes, it does. Usually on the day before it gets out of its shell. It breaks into the air cell {the hollow area you can see when you open a boiled egg} and starts breathing air for the first time.

This is how the chick does it....The chick's head is under its right wing with the tip of the beak pointed at the air cell. The large neck muscle contracts and forces the egg tooth through the air cell, and the chick takes it first breath. This is referred to as internal pipping. At this time, you may hear the chick peeping inside the shell.

On the following day, the egg tooth will break the shell and chick start to come out..that is external pipping.

Answer 2

During the last two days the chick inside the egg begins to breathe with its lungs for the first time. To do this it needs an air supply inside the egg shell. At the round end of the egg there is an air space. The chick makes a hole in this air space so that it can now breathe. The chick also calls to the hen through the shell. The hen, therefore, knows that the egg will soon hatch.

Edit: The air supply in the egg is what causes one end of a hard boiled egg to be flat. Mammals do not need to breathe because they are connected to their mothers through an umbilical cord. Chicks in an egg are on their own and must breathe at the last stages of development.

Answer 3

Yes - right before it hatches it does receive air from the spot in the egg which is "empty" - before this, it receives oxygen through the egg shell itself by diffusion across the albumen and yolk and into the chick.
Egg shells are porous - they are not solid, even though they look it.
The amount of air available in the top of the egg is hardly enough to be able to sustain the chick through the period of time it pips through the inside layer to the period of time it takes to actually pip through the shell were not SOME diffusion across the shell taking place.

Answer 4

once you breath you motivate air with lugs the place oxygen is prepared approximately RBCs and CO2 exhaled out. The hen interior the egg elect oxygen. This oxygen is derived from mom blood for the duration of the placenta and not by employing employing his lungs. He makes use of his lungs in basic terms while he come out of his shell.

Answer 5

I have lived on a farm, have had an incubator under my bed and can tell you that chicks "peep" a day or so before they hatch. Believe me, it was surprising. You can hear them loud and clear! If they can't breathe, they would not be able to cheep or "peep".

Answer 6

it's inside of an enclosed egg... how would the oxygen enter the egg, use your brain... and how would it breathe the same as a human baby if it is disconnected from its mother?

Answer 7

The same way a baby breathes in it's mom's tummy.

Answer 8

no it is living and growing in a liquid environment, just like you did, tell its heart starts beating faster and it awakes and fights to get out or dies trying.

Answer 9

as any embryo it gets life support from the mother as you did from your mother.

Answer 10

yes and with its nose
