The number of functions of protective functions of the skin

I've aquired alot knowledge after reading , and reviewing Chapter 5 . I had no idea of all the different proctective functions of the skin .I've learned that the dermis of the skin provides structual strength , and prevents tearing of the skin . I've learned that the stratified epithelium of epidermis  protects against abrasions , as the outer cells of the stratum corneum sloughs off, and are replaced by stratum basale . I't's been reinforced that skin prevents microorganisms from entering the body , as well as keeping microorgananisms , and other foriegn objects out . I really didn't realize the function of  the eyebrows and eye lashes [ to keep sweat out your eyes , and to protect eyes from other foreign objects ] . Like I said it's interesting to learn how all these funtions relate to the funtions of the hair , glands , and nails . the melanin of the skin absorbs ultravilent light protecting underlying structures from it's damaging effects . The nails even have a job , to protect the ends of fingers /toes from damage . Intact skin is important in reducing water loss because lipids acts as barriers to the diffusin of water .
