Immune System

I don't know why, but when I was a Child I was the healthiest girl in the school. I was never sick, and I hatted those kids whose lost classes because they where cooled. I wanted to do it too, but I never could miss school.

But something weird happened when I turned 18... I started to get sick every week. My last year of school I miss a lot of classes because of it. And now I have been sick this year about 7 times. It's like I can never recover from colds, It's like my normal state it's being sick.

That's why Immune System is so amazing to me.

This system is a host defense system comprising many biological structures and processes within an organism that protects against disease. It is localized on all our body and all of the cells that make up it habit different organs lymphoid. The size of it it's uncountable because it uses the blood to travel across all of our organs and detect illness, and because there are a lot of differentiated cells that works together for this system.
Every sickness start with pain, that means that immune system it's working and protecting you. Fever, for example, it's a reaction of the immune system to put microorganism that shouldn't be on your body, in a habitat that it's difficult to them to live, so they are more "stupids" and immune system it's more available to attack and kill them.
But sometimes, immune system loose the battle and microorganisms seize of your body. That's when you must to visit to your doctor.

There are some illness that attack directly this system, as leukemia and HIV. 

HIV, it's the most complicated one, because it has no cure and because you can be with this virus attacking your system a lot of years without noting it . If you want to learn more about this illness click here.
