The Epidermis

The epidermis is the outer layer of skin (the part we touch)

It does not have a blood supply

Your epidermis is replaced every 28-30 days

About 90% of house dust is made up of the epidermis which you have shed!!!!!!!!!

The main function of the epidermis is:

• Protect the body from harmful substances

• Provide a waterproof coating

• Produce melanin which helps protect skin from the suns rays

The dermis is below the epidermis

It provides strength and elasticity to the skin.

It contains lots of structures including:

Functions of the skin

Functions of the skin

The skin has 6 main functions

These can be remembered by using the acronym SHAPES.

S.H.A.P.E.S

Sensation- The skin helps us to identify heat, touch and pain

Heat regulation- The skin controls the body’s temperature

Absorption- The skin absorbs UV rays from the sun and turns them into vitamin D

Protection- The skin protects the rest of the body from all the weather elements. It is also the first line of defence against bacteria, viruses and foreign bodies

Excretion- Toxins and waste are excreted through the sweat glands which are found in the skin

Secretion- Sweat and sebum are secreted onto the skin.
