Mostly, we get cold is due to an attack of virus. Do you think we can recover is due to we have taken the medicine punctually? But why same medicine, some people just cannot easily recover and some people recover faster?

To tell you a truth that there is no medicine against virus. So what is the medicine for? It is just to let us have more time to rest peacefully and let our immune system army to take its job to battle with the virus. It is a very complicated processes how our immune system works.

With 8 simple pictures, we will easily understand about how our immune system army works against our enemy when we are sick like suffering a cold.

1. 1st step: A Macrophage, our body garbage man, is engulfing invading viruses using its numerous tentacles. This cleansing roles make the macrophage almost like a garbage man of the body.

2. 2nd step: The macrophage signals other immune cells to the battle field to help by displayng pieces of digested virus (antigen) on its surface.

3. 3rd step: A helper T cell responds to this call for help and binds to the macrophage.

4. 4th step: This union causes the release of interleukin, tumor necrosis factor and interferon.

5. 5th step: These immune chemicals cause other immune cells to proliferate. B cells multiply and produce antibodies.

6. 6th step: Killer T cels begin to shoot holes in virus-infected cells.

7. 7th step: Antibodies (immunoglobulins) lock onto the viruses, signaling complements to destroy the viruses and macrophages to engulf them.

8. 8th step: When the infection is brought under control, suppressor T cells turn off activated immune cells. Some memory cells remain so that the body will instantly defeat the same virus strain should it attack us again. Such a memory mechanism is also That is also employed and that is why we get immune to some diseases after we have the vaccination injection.

Ok, with these simple pictures, now we are easily understand why we can recover from a cold with the help of our immune system army. But, we have to bear in mind that, if and only if our immune system army is strong and then only we can win the battle, otherwise vice versa.
