Introduction To Immunity And The Immune System exam questions and answers fully solved
Define Immunity - AnswersThe state of protection against antigens ( foreign pathogens or
substances)
Example of generating immunity without inducing disease - Answersvaccinations
Chief Functions Of The Immune System - Answers1) It is our primary defense again microbes
2) It must be able to distinguish between host and foreign cells
3) It remembers prior infections and prevents illness upon subsequent exposure- long lived
immunity
Two parts of the host immune system? - Answers1)Innate (biochemical/ mechanical )
-mucous
-cilia lining
-flora
-secretions
2)Adaptive (highly specific immune response)
The innate immune system response: - Answers1) Natural or native - it reacts in a similar way
regardless of the type of microrganism (it kind of keeps the microorganism in check for the
adaptive response to get activated)
2)Responds rapidly and to the same extend with each exposure to the same microorganism
3) Our first line defense
Does not confer protective immunity - Answersthe innate response
, Innate Response Specificity - AnswersIt responds specifically but not as specifically as the
adaptive response. It responds to substances that are common to pathogens - Pathogen
Associated Molecular Patterns (PAMPS)
Innate immune response cells and binding with PAMPS: - Answers-Cells of the innate immune
response (IR) have pattern recognition receptors (PRRs) that bind to the PAMPS
(Recognition receptors on the cells of the innate system bind to the PAMPS on the pathogens/
foreign microbes)
Which type of immune response uses phagocytic cells and how can it engulf a pathogen? -
AnswersThe innate immune response uses phagocytic cells. In general phagocytic cells are able
to engulf pathogens because they have the receptors for the PAMPS
The innate immune response generate what kind of response? - AnswersAn inflammatory
response which keeps the growth of microorganism in check
Induced by exposure to a singly type of pathogen. - AnswersAdaptive immune response
How does the adaptive immune response respond to each exposure? - Answers-Response
increases with every subsequent exposure. It occurs faster and stronger.
-The response adapts to a specific pathogen
Can confer life long protective immunity against reinfection and subsequent disease after the
initial exposure - AnswersAdaptive Immune Response. After the initial exposure it takes 5-6 days
to develop life long protective immunity. That is why you need the innate response to keep the
organism in check while the adaptive response works
Cardinal Features Of Adaptive Immune Responses - Answers1) Very specific to a particular
pathogen
2)Remembers - generates memory cells that respond faster and protect against re-exposure
3)Diverse- can response to potentially any type of antigen on this planet
4) Can differentiate between self and non-self and is tolerant (unresponsive) to self tissue
