Chaparral High School. What is immunology?. Very simply, it is the study of our body’s defense against infection and disease.. Even though we are constantly bombarded by microorganisms, we rarely become sick. Why?. Sue Howell, DVM. The Immune System. www.nobelprize.org.  . Identify . potentially . injurious substances.

Current . immunosuppressors. …. …suppress the entire immune system, leaving patients more vulnerable to everyday infections and higher rates of cancer.. However, this is necessary because the immune system attacks parts of the body which are work well and are needed (in MS, myelin is targeted, causing demyelination) but we cannot isolate the suppression to just one impact of the immune system so to protect the targeted area we must lower the guard of everywhere else. .

Infectious can be passed from one person to another because of germs. What are some examples?. Key attributes of immune system. 4 attributes that characterize the immune system as a whole. specificity. antigen-antibody specificity. diversity. react to millions of antigens. memory. rapid 2° response. Main Function. The Immune System is used to prevent infection and . disease.. Using . a variety of cells and organs, the Immune System disposes of foreign or harmful antibodies through a process known as the immune response.. The specialists who diagnose and treat immune system disorders are called . immunologists. , and the specialty itself is called . immunology. .. Phagocytes. Phagocytes are often the first immune system cells . The Immune System.
