Transcript of Basic skin care and its functions

Absorption The skin actually absorbs very little; it's main function is to act as a barrier to keep things outside of the body. Heat Regulation Our bodies must maintain a temperature of 37 degrees Celsius in order to be healthy and our skin plays an important role in this process.

When we get hot, our skin sweats so we cool down.

When we get cold, our skin stops sweating, so it keeps the heat inside our bodies. Basic skin care Excretion This is the removal of waste products from the skin, like sweating. We also remove excess water and salt from our skin. Sebum oil is produced in special glands called sebaceous glands. The oil escapes onto the skin lubricating it and keeping it soft. When excessive amounts of sebum are produced it can form comedones (blackheads) or pustules (spots). Protection The skin protects our body from injury and the invasion of foreign bodies. Functions of the skin
by Amanda Strickland 2013 Structure of the skin The skin has 3 main layers The epidermis - the outer most layer of the skin; it lies closest to the surface. It mainly consists of dead skin cells which constantly shed and renew themselves

The dermis - the middle layer contains glands and the other structures that enable the skin to perform its functions

subcutaneous - this is the third layer it contains fat and connective tissue that holds the blood vessels and nerves. What temperature should the body maintain to remain healthy? What is the skins main function? Sensation The skin is equipped with many sensory nerve endings making it sensitive to touch, it feels different temperatures, pain, itching, pressure and tickling. What does the skin protect us from? Where does sebum come from?

What can form on the skin if excessive amounts of sebum are produced? Secretion Other than sweat, what else does the body rid itself of? List the 3 layers of the skin into the correct order

secretion An easy way to remember the functions of the skin is by using the acronym SHAPES
