Your Immune System J 1. AIDS is a disease that destroys the immune system. H 2. Pathogens are disease-causing bacteria. D 3. Mucus traps pathogens in the respiratory system. B 4. Antigens are proteins and chemicals foreign to the

body. I 5. Vaccines contain weakened antigens. A 6. Active immunity occurs when the body makes its

own antigens. F 7. Antibodies are substances that are made in

response to an antigen. C 8. Passive immunity occurs when antibodies are

introduced from an outside source. E 9. Lymphocytes are attacked by the AIDS virus. G 10. Enzymes destroy pathogens in stomach, pancreas,

liver.

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

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.”

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.
