Meyers – Immunology

Immunology is the area of life science concerned with how an organism fights infection and disease. To defend itself, the body makes use of the immune system, a complex set of specialised cells and organs that cooperate together to fight disease. This involves protecting us against invading bacteria and viruses, eliminating other foreign substances from the body, and destroying cancer cells. As the immune system is so important, diseases of the system can often be fatal for example HIV/AIDS. W
