Besieged Castle: The Human Body

ance. 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 mi-
crobes would be destroyed in their final destination, where they would go
if they overcame this obstacle, and how in that case they should be ex-
posed 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 Allah, Who created both the external world, and

the food in this world, and the body that needs these foods, and the sys-
tem to digest these foods, is able to create such a defence system.

Another Method: Destroying the
Enemy by Another Enemy

There are many other micro-organisms that live within the human
body which cause us no harm. What are these organisms that continue
with their own life without doing us any harm, and what is their purpose
in living within our body?
These groups of micro-organisms, which are gathered in certain
parts of the body, are called the normal microbial flora of the body. They
do no damage and even have some benefits for the human body.

These micro-organisms provide external support for the defence ar-
my against microbes. They benefit the body by preventing foreign mi-
crobes from settling in it, because the entry of any microbe into the body
