35 IMMUNITY Chapter Outline IMPACTS, ISSUES: VIRUSES,  VULNERABILITY, AND  VACCINES 35.1 INTEGRATED RESPONSES TO  THREATS Evolution of the Body’s Defenses Three Lines of Defense The Defenders 35.2 SURFACE BARRIERS 35.3 INNATE IMMUNE RESPONSES Phagocytes and Complement Acute Inflammation Fever 35.4 OVERVIEW OF ADAPTIVE IMMUNITY Tailoring Responses to Specific Threats First Step—The Antigen Alert Two Arms of Adaptive Immunity Intercepting and Clearing Out Antigen Control of Immune Responses 35.5 THE ANTIBODY-MEDIATED IMMUNE  RESPONSE Antibody Structure and Function An Antibody-Mediated Response 35.6 THE CELL-MEDIATED RESPONSE 35.7 REMEMBER TO FLOSS {IMMUNOTHERAPY} -- ? 35.8 DEFENSES ENHANCED OR  COMPROMISED Immunization Allergies Autoimmune  Disorders Deficient Immune Responses 35.9 AIDS REVISITED—IMMUNITY LOST HIV Infection—A Titanic Struggle  Begins How Is HIV Transmitted? What about Drugs and Vaccines? SUMMARY SELF-QUIZ CRITICAL THINKING Objectives 1. Describe typical external barriers that organisms present to invading  organisms. 2. Understand  the process involved  in the nonspecific inflammatory  response. 3. Understand  how  vertebrates (especially mammals) recognize and  discriminate  between  self and   nonself tissues. 4. Distinguish  between  antibody-mediated  and  cell-mediated  patterns of defense. 5. Explain the mechanisms  of immunological specificity and  memory. 6. Explain the basis for immunization. 7. Describe  some  examples  of  immune  failures,  and  identify  as  specifically  as  you  can  which   weapons  in the immunity  arsenal failed in each case. 58 Chapter  Thirty-Five
