So now that you see there is a genetic component to the immune system. . . how does the immune system work? The below are a few common types of immune responses you may experience yourself or no someone who experiences them. Answer each to the best of your ability in a Microsoft work document. Then upload this document to the CROSS TALK SECTION of the Wiki! ======

**#1:** You **fall** outside, sprain your ankle and skin your knee.

 * ==== Why does swelling occur and how? ====
 * ==== Explain the importance of these “innate” responses. ====

====** #2: Transplant Rejection ** A major problem with a transplant is the body rejecting the new/donated organ. ====
 * ==== Compare the **humoral immune** response to a transplant to a **cell mediated** response to a transplant. ====
 * ==== Explain what the MHC 1 and MHC 2 complexes are and their role in immune function. ====



** #3: HIV ** A person with HIV has their helper T cells destroyed through viral replication.

 * ==== Why is this helper T cell destruction so terrible? ====
 * ==== Describe the role of helper T cells and their effect on B and T cell stimulation. ====

** #4: Vaccination ** Explain what an acquired immune response is using vaccination as the example.

 * Why doesn’t vaccination work on the common cold or HIV.

** #5: Allergies **

 * ====== Explain the difference between an exaggerated immune response like hay fever and an auto immune response like lupus. ======
