Every
parts and parcels of our body has useful intent. They have the responsibility
they were borne to do. Any distortion of their function will bring ill-health
we have to suffer. The skin has important role for the protection of tissues,
blood, arteries, veins, ligaments, capillaries, bones and internal organs. It supports
the structure of the bones and different parts of the body with exception. It
protects all the connections that carry the blood to its destination. There
were different activities of the body inside the skin necessary to put
everything in order.
It
was considered as the largest organs. I composed of integumentary systems of
many layers of mesodermal tissues. It acted as shield against damaging
pathogen. It was the defense initiated by the body from any damages caused by
internal and external environmental sources.
It
has many layers of nerve endings that can easily determine the presence of
heat, cold, pressure, vibration and injuries to the tissues. It regulated heat
and has high level of blood supply for purpose of controlling loss of energy
due to radiation, convection and conduction activities. It dilated the blood
vessels against perfusion and loss of heat. It also constricted the blood
vessels to reduce the cutaneous blood flow and maintain heat conservation. It
controls loss of fluid due to burns and other skin injuries. It prevents
evaporation to avoid skin dryness.
The
skin has the ability to determine mood swing, physical condition and feeling
attractive. The skin becomes the depot for the storage of lipid and water. It
synthesized vitamin D through the action of ultraviolet rays to the specific
spot in the skin.
The
epidermis was used as the inlet for the absorption of oxygen, carbon dioxide
and nitrogen in small quantity.
All
nutrients that entered to the body is safeguarded by the skin that it is not
wasted. The nutrients are to be fully utilized by the different organs for
their regular and normal function. The body has colony of helpful
micro-organism especially those that are found in the digestive system. The
skin gives full support and protected the organisms to remain in the body and
not wash out and wasted.
What
is important is the epidermis to the general wellness of the body? Epidermis
was found in the surface of the skin. It was the covering made up of cells
served as the protecting body called keratinocytes, placed on top of each other
to make different sub-layers for special purpose. Any dead cells were normally
replaced regenerating itself into new cells. The cycle repeated many times when
the live cells reached to the point of its normal death and then renew again.
The
color of the skin was the result of the production of dark pigments called
melanin. It was important for the protection of the skin against harmful
ultraviolet rays. Melanin can be found at the bottom of the epidermis. It was
the cells in the epidermis called melanocytes that was responsible for skin
color.
The
dermis were composed of thicker connective tissue that gives the skin more
pliable and resistant. It regulates body temperature. It has vascular networks
responsible to carry the nutrients to reach the epidermis. It has an organ that
senses pain, temperature, blood vessels, nerve fibers, hair follicles and sweet
glands.
Inside
the skin, it contains many networks of tiny blood vessels. The blood was being
circulated to supply the skin with nutrients and oxygen. The blood vessels were
tasked to make passage of waste products away from the system.
The
skin has hair follicles growing into the dermis of epidermal tissue responsible
for the production of hairs. The visible and very tiny hairs covered the entire
body. Only the hands, lips and sole of feet were free from set of hairs. It
reacted to any changes in temperature during cold period. It stands upright in
response to the changes. The arrectar pile muscles closes the skin pores to
make it warm.
The
sebaceous gland contains quantity of oil. The oil gland secretes sebum
important in moisturizing the skin and hair. The oil was located all over the
body concentrated heavily in scalp, nose, cheek, forehead and skin.
The
sweat gland secreted sweats to cool the skin when it becomes hot. It thermo-regulate
the temperature to normal level. The structure of the sweat glands composed of
single tube, coiled body and superficial ducts, the important components in the
sweat glands.
Langerhan
cells removed and destroyed harmful materials (foreign) that are trying to
control the epidermis. It ejected the threat out of the body. Other important
parts are the meissner’s corpuscle which can detect touch and other
movements. The Pacinian corpuscles act
as receptor for pressure and vibration. It has free nerve endings that senses
pain, itchy and temperature changes.
It
is important to protect your skin at all times because skin is the gateway to
good and healthy body.
