Biology: describe the different functions of the skin?

Lynn Hollars: Evolution as origins is an adult fairy tale and many of its believers are very devout. If dna 'evolved' through slow random directionless changes, then so did computer programs. Darwin said if there was any one thing that could not have come about through slow random directionless changes, his theory was proven false. This of course was before we learned the common molecule is not a blob, but is a communication network as intricate and complex as a major metropolis, and before we knew about the dna code in all living things.. - Many folks think natural selection, which is also called mini evolution is the same as maxi evolution, also called evolution as to origins. But natural selection is merely the separation of traits or abilities "already present", not the evolving of new ones. I.e. there are many species of dogs, but no dog/cat "kind". - It's also very much a mystery how any form of life survived while taking thousands, millions of years to develop its ! survival mechanism....Show more

Bernadette Roel: protection,thermoregulation,maintain ph,undergoes asorption when exposed 4 longer time,sweating,acts as immune barrier by secreting sebum,gaseous exchange.

Lita Thammorongsa: Alone Guy has answered so I will just add something. The NMF is collagen so you can say it produces collagen..(then that description)

Asa Soho: Functions of SkinThis skin provides a protective layer for organs and tissues from pathogens, heat and light. It regulates body temperature. It stores water, fat and Vitamin D and has touch receptors that sense pain or pleasure. Skin is an excretory and absorption organ.Skin has a natural moisturising factor (NMF). Teen skin is prone to oiliness as hormones are regulating. At 20-30 years skin cell turnover provides optimum condition. At 30-40 years cell turnover starts to decrease and fine lines start to appear. At 40-50 years skin becomes more dry. Over 50 years of age, cell turnover drops by 5! 0% resulting in flaky patches and deeper lines.The skin may be! sensitive. Sensitive skin reddens easily due to environmental changes or cosmetic products. Skin can become permanently sensitive due to allergy, shaving, and use of skin care productscontaining alpha hydroxy and retinoic acid skin....Show more
