Across
3. cells with multi lobed nucleus
6. interferon secreted by leukocytes
8. develop from monocytes
9. thick substance that traps material
12. Compliment pathway which depends on the binding of antibodies
13. Abnormally high body temperature
16. is a mixture of dead neutrophils, broken down tissue cells and dead pathogens
17. secreted by leukocytes and macrophages in the presence of microorganisms will reset the hypothalamus thermostat from 98.6.
18. One of the proteins coats the microorganism and provides receptors for the macrophages
20. Complement pathway which is triggered by the interaction of several protein factors and polysaccharide molecules.
21. functions as a barrier because of keratin, which provides resistance against bacterial enzymes
23. are highly reactive chemicals with unpaired electrons that can scramble the structure of proteins, lipids, and nucleic acids
24. interferon secreted by lymphocytes
25. interferon secreted by fibroblasts
26. Similar to basophils but do not circulate in the blood
27. cells that destroy and engulf microorganisms, dead tissue etc
28. chemicals that open up channels and disintegrate the nucleus
Down
1. release sticky mucus
2. Is triggered whenever body tissues are injured
4. Can lyse and kill cancer and virus infected body cells before the immune system is activated.
5. occurs when the neutrophils squeeze through the capillary walls.
7. results in the rapid release of neutrophils from the red bone marrow
8. occurs when the neutrophils cling to capillaries in the injured areas.
10. 20 plasma proteins that circulate in the blood in an inactive state.
11. Release histamine & circulate in the blood
14. Function in protecting the body against parasitic worms
15. inflammatory chemical
19. inflammatory chemicals attract more neutrophils to the site of the injury
22. filter and trap microorganisms
29. small proteins that function to protect other cells from becoming infected.
