What do chicken eggs look like inside?

1. Eggshell: The outermost layer is the eggshell, which provides protection for the inner contents. It is composed mainly of calcium carbonate and other minerals.

2. Air Cell: At the broad end of the egg, there is an air cell, which is a pocket of air that forms as the egg cools after being laid. This air cell is important for the developing embryo during incubation.

3. Yolk: The yolk is the yellow or orange-colored part of the egg and is the primary source of nutrients for the developing embryo. It consists of a mixture of protein, fat, vitamins, minerals, and pigments. The yolk is surrounded by a thin membrane called the vitelline membrane.

4. Chalazae: Chalazae are thick, twisted strands of albumen that connect the yolk to the shell, keeping it centered and preventing it from moving excessively.

5. Albumen (Egg White): The albumen, commonly known as the egg white, surrounds the yolk and provides additional protection, nutrition, and water. It is composed primarily of water, protein, and some vitamins and minerals. The thick albumen is closer to the yolk, while the thin albumen is towards the shell.

6. Germinal Disc: The germinal disc is a small, whitish spot on the surface of the yolk. It is the site where fertilization and embryonic development occur if the egg is fertilized.

By understanding the internal structure of a chicken egg, we can appreciate its nutritional value and its role in reproduction and development.
