Fantastic Voyage | Research | How The Body Becomes Immune To An Infection

My chosen subject to explore into for Fantastic Voyage is how the body becomes immune to an infection. Therefore to get to better grips with how everything works, I have been researching into what each white blood cell does and how it helps with becoming immune to an infection. Below i have summed up what the procedure is for future use.

When a virus infects the body, the immune response would be activated. This immune response consists of different white blood cells, the first white blood cell is the Macrophage.

A Macrophage's job is to destroy any germs that it can locate, but will otherwise alert the other cells if the viral infection begins to take hold. These other cells are called T & B Lymphocites,

The job of a B Lymphocite is to create antibodies. Antibodies are a special protein that hooks onto the virus so that it is unable to replicate, it also will tag the virus so that other white blood cells will know how to kill them.

Then there is the T Lymphocite. This white blood cell has a variety of different jobs, it will raise an alarm if it notices viruses invading the body, it can help the B Lymphocite produce antibodies and lastly it is able to directly attack the cells that have been infected with a virus. 

After the infection has been eradicated some T and B Lymphocites will persist and keep an accurate memory of the virus so that if the same virus was to attack again, the body won't accidentally attack it's own cells by accident.
