Human Body : Skin -the body’s largest organ

What is Skin? : The Structure of the skin

The skin is the outer covering which protects all the delicate body parts lying underneath it.

It is the largest organ of our body which consists of several tissues including sweat glands and hair follicles.


Our skin not only provides protection to the internal body parts, but also gives us our sense of touch; it is comprised of three main layers.

The outermost layer is called the epidermis  The epidermis acts as a barrier between our internal body parts and the external environment. Therefore, it is this layer of the skin which is responsible for preventing the entry of harmful foreign agents, such as bacteria, inside the body.

Beneath the epidermis is another layer of the skin, known as the dermis which contains hair follicles, sweat glands and sebaceous glands.


The skin’s innermost layer is known as subcutis. This is where fat is deposited to act as an energy store as well as an insulator. You can read more about the skin here…
