The complex makeup, consisting
of different layers, enables the skin to fulfil
very varied tasks and functions. The skin is a
very large, versatile and flexible organ that
has a direct influence on the entire body. Among
the skin's most important functions are the protection
from exterior influences such as pressure, heat,
cold, the sun's UV rays, chemical agents and pathogens.
The skin's colonisation with a natural micro-flora
and the build up of a skin pH value made up of
sebum and sweat can keep pathogens from spreading.
If they still manage to intrude through minor
damages to the skin's surface, the immune system's
very
effective defence mechanisms will counter them.
Our thermoregulation is also controlled by the
skin. While the subcutaneous fatty tissue protects
from cold, the skin cools down the body by releasing
water during sweating processes. With the help
of numerous sensory cells, the skin supplies us
with a great amount of information related to
temperature, pain and pressure. We touch and sense
our environment with the skin.
Our skin is a very resistant organ with a high
regenerative potential. When functioning normally,
our skin renews itself every 28 days. On the other
hand, it is also a very sensitive organ, the proper
care of which is of great importance to our health.
Our mucous membranes have a similar significance.
Their main function, apart from absorbing nutrients
and secreting the metabolism's secretions and
waste products, lies in the protection from unwanted
intruders. Defence cells of the immune system
are located in the mucous membranes. Inlaid glands
produce secretions that cover the surface like
a film. This mucous makes the skin slippery and
protects it from chemical, mechanical and thermal
stimuli. Due to its physical and chemical makeup,
this special surface offers direct protection
from pathogens.
