The largest organ in your body is your

skin. Without it your muscles organ bones

and brain would be naked. The main function

of skin is to protect against infection  Skin 
keeps in moisture and keeps out sunlight,

temperature extremes and other threat. It

repairs cuts and burns with invisible trending.  

Skin stretchers and grows as you do. There

are two main layers  the 

epidermis the thin top layer of dead cells  

and the dermis the thicker bottom layer. 

Except on the palms of your hands the 

sole of your feet and your lip your 

skin covered 
with dead hair.
