Main components of Skin
Skin is essentially made up of 3 layers: the epidermis, the dermis, and the subcutaneous layer. They work together and perform the important functions like protecting the body. Let us learn more about these three components of skin.
Epidermis
Epidermis is the layer of the skin that you can see. Epidermis cells are divided into two major parts. Deep down the epidermis lives the growing cells and the outside cells are termed as dead cells. The dead cells are easily rubbed off and the growing cells take their place. These cells contain keratin which is waterproof and hard in nature. Other cells in the epidermis produce a pigment known as melanin. Melanin is responsible for the color of your skin. It also protects the skin from harmful radiation from sunlight. Darker the skin more is the protection. Hence, people with fair skin are more prone to sun burn.
Dermis
The dermis is a thicker and more elastic layer of the skin. The dermis is probably the most important layer of skin which comprises of sebaceous glands, hair follicles, blood vessels and nerves.
Sebaceous gland produces sebum oil which keeps the skin soft and waterproof. Sweat glands produce sweats and send it to the surface of the skin through small pores. Sweating is generally occurred when you are in hot surroundings. This phenomenon helps in keeping the body temperature cool. Most of the body parts are covered with hairs which are developed in hair follicle region of the dermis. Blood vessels carry oxygen and nutrients to the cells as well as carry away the waste.
Subcutaneous layer
The subcutaneous layer is mainly made up of fat which acts as protector as well helps in keeping the body warm.
