           Kill germs with heat before body dies
Acquired Immunity - Cells

           T Lymphocyte Cells - Kill specific germs

         B Lymphocyte Cells - Make antibodies


          Macrophages - Kill cells marked as bad
Acquired Immunity - Organs


 Bone Marrow - Produces all blood cells
                            - Matures B Lymphocytes
Acquired Immunity - Organs



    Thymus - Matures T Lymphocytes
