Homeostasis
a person could catch A cold again because their immune system is weak but the WON'T catch the same cold again because their anti-bodies will have killed the infection and will know that it is the same germ again and kill it.
Acquired Immune Deficeny Syndrome. (AIDS) attacks your immune system so you can't fight off infections. For example, a cold can become deadly if you catch it when you have AIDS.
The hundreds of different viruses responsible for causing a common cold all make their attack on the human body in the upper respiratory tract. The virus particles attach to the cells of the mucous tissue in sinuses, nose, mouth, eyes, throat and trachea first. The bronchial tubes and lungs also can be affected. In addition to the respiratory system and eyes, the immune system is triggered to work to rid your body of the invader with an immune response, which will employ resources from the circulatory system and blood forming organs.
It is easier to catch a cold just after getting over one, since your body is resting from trying to fight off the germs. A way to prevent getting a cold is to wash your hands a lot, and also try to get as much sleep as possible.
