Ch 31-32 Flashcards
(24 cards)
adaptive immunity
result of exposure to antigens
innate immunity
present at birth (like skin and mucous membranes)
Steps of disease
(3 steps)
- BREACH the host’s barriers
- SURVIVE the innate defense
- SURMOUNT the adaptive defense
cells in outer layer of skin
Keratinocytes
_____ cells produce mucus
goblet
_____ cells secrete antimicrobial peptides
paneth
lysozyme
hydrolyzes bond of bacterial cell wall
lactoferrin
takes iron away from microbes
bacteriocins
toxic peptides produced by normal microbiota
key difference in innate vs. adaptive defense is that
adaptive remember the foreign invader
effector response
eliminates or renders foreign material harmless
memory cells
remember the foreign material
________: responds selectively to non-self
discrimination
______: lymphocytes respond to specific non-self antigen
specificity
_______: generates enormous diversity of cellular receptors and antibodies that recognize the foreign substance
diversity
______: turned on after activation by innate response
timing
_____: response to a second exposure is so rapid that there is usually no noticeable illness
memory
discrimination, specificity, diversity, timing, and memory are all characteristics of ____ ____
adaptive immunity

maternal antibody is an example of:
- Natural Active Immunity

natural passive
active vs passive immunity
- active: person develops their own immune response to microbe
- passive: consequence of receiving immunity from another person
natural vs artificial immunity
- natural: acquired through normal life experiences
- artificial: produced purposefully though medical procedures
