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.

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 though 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.
