The structure of an egg
A. Shell composition and protective role
The structure of an egg consists of different layers, each with its own unique function. The outermost layer is the shell, which is composed primarily of calcium carbonate. The shell serves as a protective barrier, shielding the inner contents from outside contaminants and potential damage. It acts as a physical barrier against bacteria, viruses, and other microorganisms that may be present in the environment.
B. The inner layers and their functions
Beneath the shell, there are two additional protective layers called the inner and outer membranes. These membranes provide an extra layer of defense against bacteria and protect the egg from dehydration or moisture loss. They also help to prevent the entry of air and bacteria into the egg.
The innermost part of the egg is the yolk, which contains essential nutrients and proteins necessary for the growth of the developing chick. Surrounding the yolk is the egg white or albumen, which acts as a cushion and provides protection for the developing embryo. The egg white is a source of protein and water for the embryo, ensuring its proper development.
The chalaza, which appears as two thick, twisted strands in the egg white, helps to keep the yolk centered. This prevents the yolk from coming into contact with the shell, reducing the risk of contamination if the shell is cracked.
Overall, the layered structure of an egg plays a critical role in maintaining its freshness and protecting it from external factors that may compromise its safety.
