A Little About Your Skin

A Little About Skin

Skin is the largest organ of the body and weighs about 6.6 pounds.
It is a very complicated organ and performs many functions.
Basically, the skin is composed of three layers, namely: epidermis, dermis,
and subcutaneous tissue. Each layer is made up of complicated structures
that contain many specialized cells.

 Epidermis:
The epidermis is the outer layer of the skin and in turn contains 5 layers.
The outer layer of the epidermis is called the stratum corneum and it's job is to
act as a screen against outside forces.

Dermis:
The dermis is the second layer of the skin and it is the framework of the skin.
It's collagen and tissues give the skin its structure.

Subcutaneous Tissue:
The subcutaneous tissue is the third layer of the skin and 
contains fat and the larger blood vessels that supply blood to the skin.
For this reason, it is responsible for regulating the temperature of both skin and body.
