1. Cellular physiology Properties that characterize all living cells/ properties unique to speci
cell
types
2. Integrative Activities of different tissues and organs / coordination of functions of
physi- ology the human body
3. Antigen Anything capable of inducing an immunity. Anything foreign to as the
host.
4. Non specific General defense/ attack all antigens. (Inborn, first and second line
body defences defenses).
5. Specific body
de- fences Specialist/ targeted defense against one type of antigen (acquired durin
life)
6. First line of defense Nonspecific, keep every invader out/deny entry the same way
7. Second line of Nonspecific, any invader inside is attacked the same way (phagocytosis,
de- fence fever, inflammation, antimicrobial compounds)
8. Phagocytes cell eating, WBC patrol body looking for invaders, attracted to affected
site
9. Inflammation localized response, damaged cells send out chemical messages, body
re-
sponds (process supported by phagocytosis)
10. Interferon Interferes with viral replication and activate immune cells
11. Complement A set of plasma proteins that complement all aspects of the immune
response.

12. Third line of adaptive/ acquired immunity, develops on exposure to a particular
de- fence antigen, uses B and T lymphocytes made in bone marrow
13. Antibody classes IgA, IgD, IgE, IgG, IgM

15. IgG antibodies Memory antibody- quickly made in second/further infections. Smaller,
crosses
placenta
16. IgA antibodies On mucous membranes (mucosa), in blood/breast milk
17. IgE antibodies Active in allergies, protection from parasites through inflammation
18. T cells cell kills abnormal cells directly- dont make antibody
19. Cytoxic T cells Destroy foreign looking cells/cancer cells
20. T helper cells help all immune cells and activities
21. T suppressor cells suppress overactive immune response
22. Memory T cell specific with instant response to exposed antigens
23. Active immunity Makes own antibodies, memory cells have recipe, can do any time
needed. EG
24. Passive immunity Ready made antibodies given, cannot make if needed again
25. Naturally acquired active immunity
