We can compare the human body to a fortress under attack. Just as the defense of a fortress besieged by enemies is very well planned, so the human body has a perfect defense system.
No matter how clean our environment may be, we share our living space with many microorganisms. If you could examine with a microscope the room you are now sitting in, you would clearly see the millions of creatures you are living with.
So, in this sense, a human being is a besieged fortress. It goes without saying that to protect this fortress under assault a failsafe plan is necessary. Human beings were created with the perfect protection that they need; they are not defenseless against these enemies. God Almighty has created micro defense systems in the human body, protecting it from all sorts of dangerous organisms and fighting to defend it on multiple fronts.
Invasion forces have to cross the first lines of defense. Even thought the first line of defense may suffer setbacks, it will give the enemy a hard time and reduce its invasion ability.
Deterrents Waiting for Micro-enemies
The first front that the enemy must pass in the human body is our skin. The skin covers the whole body like a sheath and has many special features. One of the vital features of this miraculous packaging is its ability to protect the body from the micro-enemies that make the body sick. If we accept that the body is like a besieged fortress, we can say that the skin, with its outer layers of dead cells and the creatures that live on it, is the strong ramparts of this fortress.
One of the ways in which microorganisms reach us is through our breathing. Every moment there are hundreds of different kinds of germs in the air we breathe waiting to enter our bodies. But they are unaware of the nasal guards to repel them. A special secretion in the mucosa of the nose traps and expels between 80% and 90% of the microorganisms that that enter the respiratory system either directly or through dust, vapor or other carriers.
Germs can also enter the body through the food we eat. But our body’s defense
system is aware of this route and waits for the intruders in the stomach where the food goes. Stomach acid destroys most if not all of the germs that manage to overcome all the other obstacles and reach the stomach. The germs that make it through the stomach are destroyed by digestive enzymes produced in the small intestine.
The Truth Revealed by our Defense System
There are some important questions that have to be asked in the light of all these facts.
Who drives these external microbes to entering our bodies through our food? Who decides the route the food follows, what kind of a system must destroy the microbes, what will the microbes’ next target if they escape this deterrent, and what alternatives they take if they encounter a more powerful substance? Body cells have never been outside the body and so have not had the opportunity to examine the chemical structure of these external microbes, nor have they ever studied chemistry. So how do they know what substances will kill the microbes?
Indeed, Allah, the Lord of the heavens and Earth, created such a non-sleeping defense system protecting the human body surrounded by microbes like a besieged castle. In a verse, Allah describes His wisdom of perfect creation as follows:
He is Allah – the Creator, the Maker, the Giver of Form. To Him belong the Most Beautiful Names. Everything in the heavens and Earth glorifies Him. He is the Almighty, the All-Wise. (Qur’an, 59:24)
We must remember that the human body is helplessly exposed to microbes 24 hours a day. The fact that you are able at this moment to read this text without being adversely affected by the microbes around you, is due to the operation of the defense system inside your body inspired by our Almighty Lord. It must also be remembered that Allah has specially created germs and viruses to remind us of our helplessness against these minute structures entering a human body and making it sick and even cause its death.
