25
complement system
20 or so proteins
26
interferon
neighboring cells
27
transferrin
transports Fe to liver
28
natural killer cells
non specific lymphocytes to fight tumors
29
phagocytes
neutrophils and monocytes
30
inflammation
red, heat, swell, and pain = contain infection
31
fever
pyrogen chemicals to hypothalamus = raise temp
32
antigens
anything that provokes an immune response
33
antigens chemical nature
large proteins, not metals or plastics
34
antigens genetic recombination
results in increase diversity of antibodies
35
major histocompatibility complex
self markers not on blood
36
cell mediated immunity is what type of cells
T cells
37
CMI (T cells) differentiation
CD4+, CD8+ and memory cells
38
CD4+
helper T cells
39
CD8+
cytotoxic T cells
40
memory cells
secondary response
41
antibody immunity is what type of cells
B cells
42
AMI (B cells) differentiation
plasma cells
43
antibody shape
Y shape with 2 light and heavy chains
44
AMI plasma cells
produce antibodies (neutralize, immobilize, and opsonization) for phagocytes
45
opsonization
makes tasty
46
natural active immunity
natural antigen exposure = sneeze
47
natural passive immunity
natural antibodies = moms milk
48
artificial active immunity
shot of antigens = vaccine
49
artificial passive immunity
shot of antibodies = anti- venom
