Our immune system assist us in staying healthy by avoiding infection to spread in our body. Put simply, our immune system allows us to stay alive. The minute the immune system is overloaded or stop working properly, we become ill and may even die.



For many germs, the human body is an ideal ground and they sure would like to get inside and attack the body. It is the immune system job to keep them out. But if they get in, it is also the immune system job to find and destroy the invaders.

The first barrier these invaders encounter is the skin, which provides a great guard for the body. The skin is not easy to penetrate and produces an assortment of substances that are hazardous to the germs. Cavities such as the eyes, the nose and the mouth, which seem less difficult to invade have some defence too. They are protected by fluids that can capture sneaky invaders.

As you can see, immune systems are always busy and looking for pathogens that are trying to harm our body. It is not an easy task because the first thing the immune system has to do is to recognize and keep in mind millions of various enemies.

Secondly, it must make the right defence like secretions and cells to match up with and wipe out each one of them. This is done with the assistance of a complex communication network. Millions of organized cells get together and exchange information back and forth. Once the immune cells receive the alert, they begin creating powerful chemicals. But the fantastic ability to distinguish the body' s own cells and the foreign cells is the key to a healthy immune system.

This is important since without this ability the immune system can not have a clue of which organisms to assault or not. This is done with the assistance of "marker molecules". When the immune system defenders encounter organisms transporting markers that say "foreign", they instantly send an attack. The faster the response the better they can eliminate the germs.
