Your skin does important functions that allow you to live a normal life; you might not notice it happening but be sure that your skin is performing its part to keep your body healthy. Keep reading and enjoy the following interesting facts about skin.
Skin is human body’s largest organ.
It performs a range of different functions which include protecting your bones, muscles and internal organs, protecting your body from diseases, helping you to feel and react to heat and cold and using blood to regulate your body heat.
The 3 layers of mammal skin are epidermis, dermis and sub cutis.
The outer layer of your skin is the epidermis, thickest on the palms of your hands and soles of your feet.
The subcutis is the deepest layer of your skin, stores fat, and also contains blood vessels, hair follicle roots and nerves.
If skin is badly damaged then it might try to heal by forming scar tissue. Scar tissue is not similar to normal skin tissue; it often appears discoloured and lacks sweat glands and hair.
The colour of human skin depends on the amount of melanin that the body produces. Small amounts of melanin results in lighter skin while large amounts lead to dark skin.
Areas which experience repeated friction or somewhat pressure might form tough, thick skin known as a callus.
A large amount of the dust in your home is nothing but dead skin.
All mammals have some hair on their skin.
Rhinoceros’s are protected by thick skin which could be between 1.5cm and 5cm deep.
