1. Your Immune System  J 1. AIDS is a disease that destroys the immune system.  H 2. Pathogens are disease-causing bacteria.  D3. Mucus traps pathogens in the respiratory system.  B4. Antigens are proteins and chemicals foreign to the body.  I5. Vaccines contain weakened antigens.  A6. Active immunity occurs when the body makes its own antigens.  F7. Antibodies are substances that are made in response to an antigen.  C8. Passive immunity occurs when antibodies are introduced from an outside source.  E9. Lymphocytes are attacked by the AIDS virus.  G10. Enzymes destroy pathogens in stomach, pancreas, liver.

2. Antibiotic Resistant Bacteria  11. Why does antibiotic resistance occur?  Some are naturally resistant. Some mutate to develop a resistance.  12. Describe the three examples of the incorrect use of antibiotics.  1. A prescription is not completed.  2. Antibiotics are taken when a patient doesn’t need them.  3. Repeated exposure to cleaning products has made bacteria stronger over time.  13. What are the three types of bacteria that have developed a resistance to antibiotics?  1. Tuberculosis  2. Staphylococcus aureus  3. Streptococcus

3.  One of your patients is refusing to finish his antibiotic prescription. What would you tell him to make sure he finishes his medication?  “I would explain to the patient that he may become sick again if he doesn’t finish his medicine. I will also tell him that not taking all of his antibiotics may also result in antibiotic-resistant pathogens.”

4. How does the Immune System work? Antigens (foreign substances) are detected. Antibodies are present to attack antigens again. Immunizations introduce antigens to a person’s body. T cells destroy antigens that have been “tagged” by antibodies. Antibodies neutralize toxins and kill bacteria, viruses, and other infected cells.
