The human body is simply exceptional, it has various homeostatic
mechanisms which functions to keep us alive and comfortable.
The human body was designed in such a way that makes it both
anatomically and physiologically adept to changes in the
environment.
Have you ever wondered what keeps humans alive? The body is
kept alive by numerous systems and organs that work together.
1. The skin sheds about 30,000 to 50,000 skin cell, every single
minute of your life. This mechanism is important in getting rid of
dead skin cells and harmful organisms on the surface of the skin.
Note that only the eyes does not shed. Shed skin are quickly
replaced
2. When a woman is pregnant, and an organ in her body is
damaged. The baby in the womb sends stem cells to repair the
damaged organ.
3. The normal human body temperature is 37 degrees Celsius. If
the body is to go markedly above or below this number, it will lead
to death. However the body does alot of amazing things that
stabilizes the body temperature despite the environmental
temperature. Such as, shivering, sweating, vasoconstriction and
vasodilation.
4. The stomach produces acid secretions that can excoriate the
stomach lining. However your body grows an entirely new stomach
lining every 3-4 days.
5. Your mind forgets some information to protect you from
overload of information and emotional distresses. This action helps
you to think more quickly and assimilate new information better.
6. The body has the ability to self heal. If you are cut or injured,
bleeding is immediately stopped in minutes. Destroyed cells are
immediately regrown. This is very important because, we would
have all been dead if not for this amazing mechanism.
7. In cases of extreme starvation, how does the body react to keep
us alive? It first all uses the glucose and stored glycogen to keep
the body going. This lasts for about 6 hours, before it turns to the
fats and ketone bodies, before moving on to proteins. This
mechanism can help you survive hunger for up to 70 days.
However, that depends on some factors like weight, and amount of
fat present.
8. When the body is faced with life threatening situation, it secretes
hormones like adrenaline and cortisol. This reaction is known as
acute stress response. During this reaction, the released hormones,
speeds the heart rate, slows digestion, and increases blood flow to
major muscle groups, and changes a lot of other autonomic
nervous functions, that gives you a burst of energy and strength.
This response is essential in a flight or fight situation.
9. The body has the ability to recognize former pathogens that has
attacked the body previously and destroy them. This is known as
acquired immunity.
10. The liver is extremely important in body, it does a lot of
metabolic and homeostatic functions. The liver
has the ability to regrow if part of it is removed due to injury,
disease, or surgery. It can even grow to be just the right size for
the body it’s in, isn't it amazing?
Conclusively, we should always appreciate our magnificent body,
by acknowledging it's awesome abilities. Thanks!
