  II. Innate Immunity
      A. Defined 
         1. + rapid
         2. - limited recognition
         3. - same response level
      B. Components

         2. cells
         3. blood proteins
         4. cytokines
      C. Defense lines

 III. Adaptive immunity
      A. Defined
            a. - delay
            b. + large recognition
            c. + increase in magnitude
      B. Types of adaptive immune responses
         1. humoral
               1) antibodies
               2) antigens
            a. active immunity
               1) naive
            b. passive immunity
         2. cell mediated
