25
Antibody produced by B cells during primary exposure
IgM
26
Antibodies produced by B cells upon subsequent exposures
IgG
27
Between IgG and IgM, which is the bigger one and which is smaller?
IgM is bigger, IgG is smaller
28
Which antibody is too large to leave the blood?
IgM
29
true/false: our second immune response is much stronger than the first
true
30
Why is our second immune response stronger than the first?
The antibody IgG is small enough to leave the blood, allowing it to fight infections all over the body. There are also more antibodies and memory cells ready
31
Antibody found in breast milk and body fluids
IgA
32
Transfer of antibodies from one person to another
Passive immunity
33
placenta and breast milk are examples of what type of passive immunity?
Natural
34
Short term immunity
Passive immunity
35
Gamma globin and some antioxidins are examples of
artificial passive immunity
36
Long lasting immunity which involves building up the immune system with memory cells
Active immunity
37
Chicken pox is an example of
natural active immunity
38
Vaccines are examples of
artificial active immunity
39
antigen which makes b cells stimulate the antibody IgE
allergens
40
The molecule which releases histamine
IgE
41
Histamine is released when the antigen ______ presents itself by______
allergen, IgE
42
What cells do allergy shots build up?
Ts cells - suppressing our immune response
43
Examples of autoimmune diseases include
Multiple sclerosis, rheumatoid arthritis, lupus, and rheumatic fever
44
Aids attacks which cells?
Th cells
45
several lymph vessels at a sac-like structure
cisterna chyli
46
Where does the thoracic duct start
junction called cisterna chyli
47
Lymph nodules and nodes are often grouped in what areas
cervical, ingual, axilla
48
Specialized lymphatic organs/ tissues
thymus, red marrow, tonsils, peyers patches, spleen
49
mixture of T-lymphocytes and hormone producing cells that help to activate them
Thymus
50
2 distinct areas of the spleen
White pulp, red pulp
51
Strands of lymphocytes clustered around branches of the splenic artery
White pulp
52
When RBC recycling occurs
Red pulp
53
Acts as a blood resevouir incase of blood loss
spleen
54
Innate defenses are
non specific defenses
55
What are the two categories of innate defenses
skin barriers, internal defenses
56
skin defenses of innate defense are
skin and mucous membranes
57
Internal defenses of innate defenses are
phagocytes, inflammation, natural killer cells, fever, antimicrobial proteins
58
Defenses that are specific to a particular antigen
Adaptive defenses
59
Adaptive defenses are divided into two groups
Humoral immunity, cellular immunity
60
Humoral immunity involves
B cells
61
Cellular immunity involves
T cells
62
Mucous ,nasal hair, ciliated epithelium, and certain reflexes help the body
get rid of pathogens
63
destroy pathogens or protect uninfected cells.
antimicrobial proteins
64
proteins which are produced by infected cells that can protect nearby cells from viral infections
interferons
65
rip holes into target cells. can sometimes attach to microorganisms surface via triggers. immune system antibodies tell them which cells to target
complement proteins
