15. The Immune System
vs.
a pathogen.

16. 1. Once a pathogen (bacteria or virus) enters the body, the immune system is alerted by the Helper (Killer) T-Cell. The job of the T-Cell is to detect any foreign substance that may be in the body that should not be there.
3. The anti-bodies beat up the pathogen until it can no longer defend itself.
2. The T-Cell than calls the B-Cells which produces antibodies.
4. The macrophage then comes in and engulfs up the weakened pathogen.

HIV Virus

18. The Immune System vs. HIV Activity
With your group, present a re-enactment of how the HIV virus defeats the immune system using poster boards with the words: SKIN, HELPER TCELL, BCELL, AND ANTIBODIES.

19. 1. The T-Cells go to the HIV virus immediately to get rid of the problem, but the HIV virus tricks the T-Cell and attaches itself to the T-Cell.

20. 2. The HIV Virus then proceeds to release genetic material into the T-Cell. All the while, the T-Cell believes the virus is gone. This is why sometimes it may take up to six months before HIV can be detected.
3. While this is happening, the HIV Virus destroys all signals that the T-Cell uses to sent to the B-Cell to produce antibodies.

21. 4. The HIV Virus than finally decides to break out.
5. The T-Cell realizes there is a problem, but can no longer call the B-Cell to produce antibodies. The HIV virus continues to reproduce. Eventually the immune system can no longer defend itself.
