In order to keep disease free body one must know the basics of how the immune system works.

1. The air that we breathe consists of numerous germs such as bacteria and viruses. Human body always tends to fight against these microorganisms so that the body doesn't catch infections like cold or flu. When we get viral infection, is the reason our immune system failed to protect it at first place. After getting recovered is the sign that the immune system gets to learn about it and give our body further protection, if it tries to infect our body again. Without this immune system, one just cannot recover the infection and probably dies. This is the reason why people in the past had very short life span of about 40 years maximum.

2. When a mosquito bites us, we can see a visible red and itchy bump on the affected area. This is the way our immune system to defend our body work at its best.

3. When we get injured, all kinds of microorganisms try to penetrate our body through the skin. Our immune system eradicates these invaders and our skin gets clotted. Although there are rare cases when this system misses out something and the cut gets inflamed and often fills with pus in response to infection that the immune reacts while doing its job.

4. Sometimes the immune system responds in an unexpected manner which causes problems. Like some people are intolerant to certain food items or metals. This is the immune system that overreacts to certain triggers and other people do not experience at all. Some of the disorders like diabetes and arthritis have this immunity system error in which the immunity system mistakenly predicts its own cells as 'foreign invaders' and contiguously damages it.

5. Other factors like organ transplantation are much more difficult than expected because it is the immune system that often denies the new transplanted organ.
