Chapter 26: Immune System and Other Defenses

This list is only a study guide, NOT a complete list of all the material on the test. Any material discussed in class is potential test material. Do not forget to go over your lecture notes and power point slides on ecampus.

1. What physical barrier and non-specific defenses help to prevent infection? How is a “non-specific” defense different from a “specific” defense?

2. Non-specific immunity is also called ___ immunity while specific immunity is called _____

3. Describe the roles of complement proteins, cilia (in lungs), natural killer cells and phagocytes. How are these non-specific defenses?

4. Describe the inflammatory response. Describe how this happens.

5. How is the immune system (and inflammation) related to allergies?

6. What is an antigen? How does your immune system recognize it?

7. What is an antibody?

8. Know the difference between B cells, killer T cells, and helper T cells. What do they do? Where are they produced, what type of immunity they provide, how do they kill foreign organisms.

9. Describe how the immune system responds to an infection...basically know how a B cell is activated and how it makes antibodies.

10. What is the difference between a primary and a secondary immune response?

11. What is a vaccine? What is it made up of?

12. What is active immunity and passive immunity?

13. What are the immune system disorders? Know relationship between AIDS and immune system.

14. Allergy is immune system responding to normally harmless substances. ____ cells release histamines.

15. Know the autoimmune diseases we discussed in class…Know what cells/tissues are affected by each of those diseases.

After studying your notes, slides and after addressing the above questions try to use the below questions as a self-quiz. It is not a good idea just to find and write down the answers for the below questions but if used as a self-quiz it will increase your self-confidence in answering test questions

From the word bank below, assign each term to the immunity heading with which it is associated.

|Antibodies in breast milk generalized response short-lived antibodies |

|lymphocytes specific Barriers |

|stomach acid, saliva, tears memory cells Complement proteins |

|first line of defense non-specific Inflammation |

Passive immunity Innate immunity Adaptive immunity

Match the description on the left with the term on the right by writing the correct letter in each blank.

|_____1. A disease that destroys the immune system |Active |

|_____2. Disease causing bacteria |Antigens |

|_____3. Traps pathogens in respiratory system |Passive |

|_____4. Proteins and chemicals that are foreign to the body |Mucus |

|_____5. Contains weakened pathogens |Lymphocytes |

|_____6. Immunity occurring when your body makes its own antibodies |Antibody |

|_____7. Substance made in response to an antigen |Enzymes |

|_____8. Immunity occurring when antibodies are introduced from an outside source |Pathogens |

|_____9. Cells attacked by AIDS virus |Vaccine |

|_____10. Destroy pathogens in stomach. pancreas and liver |AIDS |
