INNATE IMMUNITY EXAM QUESTIONS
WITH VERIFIED ANSWERS. A+ GRADE
2025/2026.
Immunity - ANS Ability of an organism to resist infection
Innate Immunity - ANS Nonspecific immunity
-The bodies built an ability to recognize and destroy pathogens
-includes physical, chemical and cellular barriers
Adaptive Immunity - ANS Specific immunity
-the acquired ability to recognize and destroy pathogen
-requires past exposure of the immune system to the pathogen
-immunologic memory
Immunologic Memory - ANS future exposure to same pathogen elicits a quicker and more
robust response
Response time-Innate immunity - ANS Minutes/hours
Response time-Adaptive immunity - ANS Days

, Specificity-Innate immunity - ANS specific for molecules and molecular patterns associated
with pathogens
Specificity- Adaptive immunity - ANS highly specific, discriminates even minor differences in
molecular structure, details of microbial or non microbial structure recognized with high
specficity
Memory response- Innate immunity - ANS none
Memory response- Adaptive immunity - ANS persistent memory, with faster response of
greater magnitude on subsequent infection
Self/nonself discrimination- Innate immunity - ANS perfect, no microbe-specific patterns in
host
Self/nonself discrimination- Adaptive immunity - ANS very good, occasional failures of
self/nonself discrimination result in autoimmune disease
Major cell types-Innate immunity - ANS phagocytes (monocytes, macrophages, neutrophils),
natural killer (NK) cells, and dendritic cells
Major cell types-Adaptive immunity - ANS T cells, B cells, antigen-presenting cells
Characteristics of the adaptive immune system - ANS Specificity- each cells is highly specific
for a particular epitope
Diversity- together there is a tremendous diversity
Memory- long-lived memory cells created during each response
Self/nonself discrimination- negative selection in development
External barriers to microbial invasion - ANS skin and mucous membranes (line the
alimentary, respiratory and urogenital tracts, eyes)
