The document discusses the immune system and diseases, including infectious diseases caused by bacteria, viruses, protists, and fungi that are spread through various means. It describes the immune system's nonspecific defenses like the skin and inflammatory response, as well as its specific defenses through antibodies. The document also covers allergies as an overreaction of the immune system, autoimmune disorders where the immune system attacks the body's own cells, and cancer which occurs when cell growth controls fail. It lists chemotherapy, radiation, and surgery as common cancer treatment methods.

6. Allergies The most common overreaction of the immune system are known as allergies. Allergies result when antigens from allergies, such as the figures to your right. Vicky

7. Autoimmune System When the immune system make a mistake and attack the body’s own cells, it produces an autoimmune system Vicky

8. Cancer Cancer begins when something goes wrong with the controls that normally regulate cell growth and division. Vicky
