THE IMMUNE SYSTEM

3. produced in inflammation when phagocytes kill pathogens
4. type of cell that surrounds, ingest and kills pathogens
5. cell that creates antibodies
6. mode of transmission that involves an infected person passing on the pathogen by touching them
7. can inhibit the growth of some bacteria in the second line of defense
12. protective reflex of the upper digestive system
13. anything that causes the body to stop working properly
15. group of cells released during inflammation
18. injects toxin into infected cells
19. disease causing organism
23. type of pathogen that causes Malaria
25. protective reflex of the lower respiratory system
26. redness and altered function are symptoms of this
29. type of pathogen that has to invade host cells to survive

1. immune cell that attracts phagocytes
2. immune cell that increases blood flow and blood vessel permeability
8. chemical containing part of a dead pathogen that triggers an immune response without causing the disease
9. cell that intensifies phagocyte and other immune cell activity
10. water proof barrier that contains oils and sweats
11. type of pathogen that is treated with antibiotics
14. viruses don't respond to antibiotics because they have a:
15. immune cell that responds to re-exposure to pathogens
16. a phagocytic cell involved in cell mediated immunity
17. immune cell that prevents blood clots
20. type of pathogen that spreads via spores
21. protein that binds, clumps together and dissolves pathogens
22. mode of transmission that involves another organism transferring a pathogen from one person to another
24. immune cell that stops immune response once completed
27. occurs when our body mistakes harmless substances as a pathogen
28. a mechanical barrier that prevents the transmission of disease
