To sumerise, there are many classes of white blood cells which play different roles in fighting disease. These include producing antibodies and engulfing bacteria. Cytotoxic T cells are responsible for killing virally infected cells.

All white blood cells are known officially as leukocytes. White blood cells are not like normal cells in the body -- they actually act like independent, living single-cell organisms able to move and capture things on their own. White blood cells behave very much like amoeba in their movements and are able to engulf other cells and bacteria. Many white blood cells cannot divide and reproduce on their own, but instead have a factory somewhere in the body that produces them. That factory is the bone marrow.

They produce antibodies when the organism gets infected with a disease. This means that if the organism gets infected with the same disease again it will be fought off without the organism getting ill. They also produce antitozins which neutralise the toxins which invading bacteria/viruses produce.

when pathogens (the virus) enter the body they begin to multiply, soon the white blood cells will locate the pathogens using the antigens on the pathogen the patogens use the antigens as a way of identifying the patogen white blood cells called lymphocytes produce antibodies and antitoxins white blood cell caled phagocyte will will injest the pathogen and exit the body as puss in a wound. (Antibodies attack the antigen so the phagocyte can injest the pathogen.) (Anti toxins neutrilise the toxins yhe pathogen create.) (HIV hides its antigen so white blood cells cant find it and defend against it)

They fight diease by making antibodies and "eating" the virus that is in the body

Phagocytes engulf and digest bacteria/viruses.
