- 10. Body's process of developing antibodies against certain diseases
- 13. Protein compounds released by white blood cells to react with and destroy antigens
- 14. Body's immunity to pathogens developed throughout life by natural exposure or vaccination
- 15. Resistance that organisms have to most diseases, passed on genetically
- 16. Isolate sick people, often in special facilities, place where such people are isolated

- 2. Drug that fights bacterial infections by either killing bacteria or preventing them from reproducing
- 3. Diseases that spread through the population faster and more widely than would normally be expected, not as widespread as pandemics
- 6. Diseases that affect a large proportion of the popultion in many countries, farther reaching than epidemics
- 8. Antibodies introduced into the body to create immunity
- 9. Structures attached to all cells, they help the body's immune system identify pathogens
