Protection in Respiration
One of the courses our enemies
take to enter our body is the respiratory tract. Hundreds
of varied microbes, which are present in the air we
inhale, try to gain entry to the body through these
passages. However, they are unaware of the barrier set
up against them in the nose.
special secretion in the nasal mucous retains and sweeps
out about 80-90% of the micro-organisms that gain entry
to the respiratory system directly or through dust particles
or other substances.
In addition, the tiny hairlike
structures (cilia) on the surface of the cells of the
respiratory tract beat upward, causing a current that
carries foreign particles to the throat where they are
swallowed and disposed of by acid in the stomach. The
coughing reflex and sneezing facilitate this function.
The microbes that are able to
surmount these barriers and reach the alveoli (lung,
bronchus and gingiva) will be ingested by phagocytes.
After this phase, phagocytes become mobile and drift
upwards with the microbes they have ingested to be finally
discharged from the body in different ways.
Each time you breathe, as you
are doing now, a war is fought at the border gates of
your body of which you are completely unaware. The guards
at these border gates fight with the enemy to the death
to protect your health.
Protection in the Digestive System
Another vehicle by which microbes
gain entry to our body is our food. However, the guards
of our body, which are aware of this method used by
the microbes, await them in the region where the food
finally ends up, which is the stomach. They also have
a surprise for the arriving microbes, which is the gastric
acid. This acid is quite an unpleasant surprise for
the microbes which have overcome all obstacles and reached
the stomach. The majority, if not all, of the microbes
are defeated by this acid.
Some microbes may overcome this
obstacle because they have not made enough contact with
the gastric acid, or they have showed resistance. However,
these microbes are again subjected to further conflicts
with other guards situated on their way. Now, another
surprise is at hand for them: the digestive enzymes
produced in the small intestine. This time, they cannot
get away as easily.
As we have seen, the human body
has specially created guards, which protect the human
body in every phase of the microbes' assaults.
There are now some important
questions raised by this examination.
Who established that microbes
living outside would try to penetrate our body through
foods, which route the food would follow, how microbes
would be destroyed in their final destination, where
they would go if they overcame this obstacle, and how
in that case they should be exposed to stronger measures?
Is it the body cells, which have never been out of the
body, and therefore, have no chance of examining the
chemical make-up of the microbes outside, and which,
moreover, have not received any training in chemistry?
Definitely not. Only God, Who
created both the external world, and the food in this
world, and the body that needs these foods, and the
system to digest these foods, is able to create such
a defence system.
