Q

why does inflammation cause swelling

A

higher permeability -> more fluid to penetrate tissues -> edema/swelling

extra fluid -> higher pressure -> compressing ends of tissues

Q

Clonal expansion is

Q

plasma cells

A

secretes particular type of protein - known as antigen/humoral immunity

24
Q

to stmte immune rsp ->

A

pathogen must overcome body’s general protective defense

  • proves that it can survive past auto -> needs more assistance to kill off
25
pathogen entry points include
superficial mucous membranes - nose, mouth, eyes
26
T/F physical elimination of invading pathogens is possible
TRUE - ex. urine passes through urethra
27
innate immunity
non-specific rsp (phagotic cells eat bacteria) body itself is able to take care of the pathogens
28
in tissues - phagocytic cells are
present to swallow any bacteria that passes physical defenses
29
T/F neutrophils are NOT involved in phagocytosis and do not provide initial rsp
FALSE - neutrophils provide initial rsp (front line) and ARE involved in phagocytosis (body detecting antigen)
30
what do neutrophils NOT act as
antigen-presenting cells - dont induce another immune rsp
31
tissue macrophages come from
monocytes leaving bloodstream
32
tissue macrophages ____ to ____ activity & ___ dmged areas
react neutrophil invade
33
T/F cells like tissue macrophages are HIGHLY EFFECTIVE in phagocytosis
TRUE
34
how long does it take for body to produce substantial amt of antibody after being exposed to antigen
3-14 days
35
how long do plasma cells live for
4-5 days w/enormous demand
36
difference b/w clonal cells and plasma cells
clonal cells can grow into MEMORY cells - plasma cant
37
advantages of memory cells
- live long - fast rsp when same antigen next time - less antigen needed - memory - literally, rmb antigen and how to kill
38
secondary reaction
- prevents anml from dvping a 2nd time - common diseases (flu/cold) = many strains = diff e/t = don't stmt 2nd rsp
39
what type of lymphocyte cells does body have large supply of
T cell and B cell
40
what lymphocyte cell comes from bone marrow and matures in thymus gland
T cell
41
T/F not every T cell is responsive to a specific antigen determinant
FALSE EVERY T cell = rspve
42
how does cell-mediated immunity typically work
works in conjunction w/humoral immunity
43
what are the 2 types of T cells
T-helper cell cytotoxic cell
44
how does t-helper cells stmte immune rsp and how do they detect cancer cells
release cytokines cancer cells = diff surface antigen
45
Can B-cells become memory B cells?
YES - but NOT LONG-LIVED - not exactly like memory cells from clonal cells
46
disease protection can come from
natural infection or vaccination -> active immunity
47
how does vaccine provide protection
prepares anml to rspd fast to disease
48
T/F vaccine/immunication are based on memory cell dvpmt
TRUE
49
name the 2 types of vaccines and how they work
modified live vaccine - from pathogen's modified strains - strain = weakened => replicate but not harmful killed vaccine - dead pathogen - can't divide, but still has antigen to induce immune rsp
50
what dvps when transferring antibodies from 1 anml to another
passive immunity
51
what is colostrum
- 1st milk from mom during pregnancy - very rich in antibodies (whatever mom has, passes to kid) - how kid defends itself as a new born
52
antibodies are digested & _____ through normal ____
inactivated digestion
53
antibodies are
protein molecules
54
if antibody is absorbed through blood stream, newborn will have
instant immunity
55
T/F ability to absorb antibodies is rapidly INCREASING
FALSE - rapidly descreasing
