What does the skin protect?

Answer 1

The skin protects the skin from pathogens, which are known as bacteria, viruses and such. It also keeps your whole body in place, working together with the muscles and bones. But the skin is prone to damage from the sun.

Keratin in the skin protects underlying tissues from microbes, abrasion, heat and chemicals. Lipids released by lamellar granules inhibit evaporation of water from the skin surface, thus protecting the body from dehydration. oily sebum prevents hairs from drying out and contains bactericidal chemicals that kill surface bacteria. The acidic pH of perspiration retards the growth of some microbes. Melanin provides some protection against the damage effects of UV light.

Skin is the major organ in our body.it helps the body in many ways.

• PROTECTION;it protects the body from external environment such as chemicals,physical agents such as harmful sun i.e is ultraviolet rays and biological agents such as microbes.
• IT protects the internal organs and also forms water proof layer by depositing melanin on upper layers of cells.
• upper surface of skin contains specialised phagocytic cells such as langerhans which attack foreign substances and present them to lymph system.
• it also contains hairs.
• it also kills various microbes present on skin with their special secreations and kills them by which it produces special characteristic odor for each type of person
• it protects from harmful rays coming from skin by producing a special pigment called melanin.
• it also helps in secretion of some waste materials in form of sweat.
• it protects our body by maintaining HOMEOSTASIS that is by regulating body temperature.it controls temperature by excreting sweat during increased temperature conditions and also by contraction and dilation of blood vessels producing a cooling effect.

Answer 2

Skin protects from UV radiation, which could damage DNA. It also keeps nasty things like environmental poisons and bacteria out of the body. Skin also stops us from drying out. It prevents mechanical damage such as bumps.

Answer 3

The skin consist of 3 main layers, and because of these layers, the skin cannot let infection in. most cuts/burns etc only scrape the top layer of dead cells, if deeper it cuts into the epidermis, wish still has a resistance to infection, its only the dermis which is extremely frail to infection, hope i helped
