What are the parts of chicken egg?
The actual egg has 8 different parts: Shell, Yolk, Vitelline Membrane, Air Cell, Chalazae, Albumen, Inner Membrane and Outer Membrane. Each part of the egg serves a different purpose.

What are the three basic parts of a chicken egg?
An egg basically consists of three parts: a shell, an egg white and an egg yolk. An egg from a hen consists of approximately 2/3 egg white and 1/3 egg yolk.
What are 5 egg parts?
The structural components of the egg include the shell and shell membranes (10 percent); the albumen or white (60 percent), including the thick albumen, the outer thin albumen, the inner thin albumen, and the chalazae; and the yolk (30 percent).
What are the parts of a chicken egg and their functions?
Thick egg white: the thick egg white is thick and cloudy and found around the yolk. Yolk: the yolk provides the chick with the food it needs. Blastodisc: this is where the egg will potentially be fertilised. Air space: this is where the chick draws its first breath before pecking through the shell.
What is the inside layer of an egg called?
The egg white is known as the albumen, which comes from albus, the Latin word for “white.” Four alternating layers of thick and thin albumen contain approximately 40 different proteins, the main components of the egg white in addition to water.
What is the membrane in an egg?
Eggshell
Eggshell is made almost entirely of calcium carbonate (CaCO3) crystals. It is a semipermeable membrane, which means that air and moisture can pass through its pores. The shell also has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust.
What are the protein contents in egg?
On average, a medium-size egg contains around 6.4 grams of protein which makes up around 12.6% of the overall edible portion.
Where does the chick take its first breath?
The chick’s head is under its right wing with the tip of the beak pointed at the air shell. 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.
What is the thick white part in an egg?
chalaza
It’s called a chalaza. There are two chalazae in an egg, one that suspends from the top of the shell and one from the bottom. Essentially, these rope-like structures are made up of protein, and they attach to the yolk to protect it from bumping into the sides of the eggshell.
What is the white speck in an egg?
The chalazae (plural) are rope-like structures made of protein that act as a support system for the yolk. It keeps the yolk suspended in the center of the egg and safe from pressing against the shell or settling on one side of the egg. When cracking an egg, there’s really no need to remove the chalazae.
What makes up the shell of a chicken egg?
Looking at the egg from the outside we see the shell, which is a hard, protective covering made of calcium carbonate. The shell is porous. (There are about 7,000 pores in a chicken eggshell.) This allows the transfer of gases through the shell.
What is the internal albumen of a chicken egg?
Internal albumen (Chalaziferous albumen) — The inner thick white (chalaziferous layer) is a dense, matted, fibrous capsule of albumen around the vitelline membrane of the yolk. The matted fibrous capsule terminates on each end in the chalazae, which are twisted in opposite directions and serve to keep the yolk centered. 13.
How many pores are there in a chicken egg?
(There are about 7,000 pores in a chicken eggshell.) This allows the transfer of gases through the shell. Carbon dioxide and moisture are given off through the pores and are replaced by atmospheric gases, including oxygen.
What are the different colors of chicken eggs?
Shell Color: Chicken eggs come in a rainbow of colors, from blues and greens to whites, browns, and even speckled varieties. The most common commercial eggs you find at the store or farmers market are white and brown. Contrary to egg lore, there is virtually no health difference between lighter and darker-shaded eggs .
