What is the primary purpose of a 'good' amount of inflammation in response to an infection?
- To get the immune system going (correct)
- To stimulate the production of cytokines

- To initiate an adaptive immune response
What is a characteristic of the innate immune system's response to a microbe?
What is a characteristic of the innate immune system's response to a microbe?
- It is unique each time a microbe is encountered
- It is specific to the type of microbe
- It responds the same way each time a microbe is encountered (correct)
- It is only activated after the adaptive immune response
What can occur when the innate immune responses fail to contain a pathogen?
What can occur when the innate immune responses fail to contain a pathogen?
- The pathogen may spread and initiate an adaptive immune response (correct)
- The pathogen is eliminated by the innate immune system
- The adaptive immune response is suppressed
- The immune system becomes tolerant to the pathogen
