Is the egg fully packed?

New Delhi: Oxygen is needed for any organism to live. Whether it is human, animal or any bird. But you must have seen that birds lay eggs. The bird’s egg is completely sealed. But have you ever thought that when the egg is completely closed, then how does the chick ie embryo remain alive inside it? Where does he get oxygen after all? Let’s tell the truth of this.

oxygen between the membranes
It took many years to reach this question. You must have noticed that the egg is a hard shell, on seeing which it looks completely packed. But there are membranes under it. Which we don’t usually see. There is a small air sac between the membranes. Oxygen is filled inside it.

You will be surprised to know that there are more than 7,000 holes in the shell of a chicken egg. If you look carefully at the egg with the help of a magnifying glass, you will see small holes inside it. Of these, not only does oxygen go in, but carbon dioxide also comes out.

Not only this, with the help of these cells, the chick also gets water. After the embryo is fully developed, the winged infant strikes repeatedly with its beak to come out of the cage as an egg. Due to this, a crack occurs in the middle of the egg or at any other wide site, from which the chick comes out. When it comes out, it is wet with a liquid. But soon it dries up on exposure to air.
