Adaptive immunity is slow initiation, rapid therafter?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Adaptive immunity is characterized by a slow initiation phase followed by a rapid response. This is because adaptive immune responses require the recognition and activation of specific immune cells, such as T and B cells, which takes time. Once these cells are activated, they can rapidly proliferate and differentiate into effector cells that can eliminate the pathogen or infected cells. This process allows the adaptive immune system to mount a targeted and specific response to a particular pathogen, but it may take a few days to fully develop. Therefore, the statement that adaptive immunity is slow initiation, rapid thereafter is true.Rate this question:
-
- 19.
Innate immunity causes inflammation?
Correct Answer
YesExplanation
Innate immunity causes inflammation because it is the body's first line of defense against pathogens and injury. When the immune system detects a threat, it triggers a cascade of events that result in inflammation. This response is essential for recruiting immune cells to the site of infection or injury, promoting tissue repair, and eliminating pathogens. Inflammation is characterized by redness, swelling, heat, and pain, which are all indications of the immune system's active response to protect the body.Rate this question:
- 20.
Adaptive immunity causes inflammation?
Correct Answer
NoExplanation
Adaptive immunity does not directly cause inflammation. Inflammation is primarily triggered by the innate immune response, which is the first line of defense against pathogens. Adaptive immunity, on the other hand, involves the activation of specific immune cells (such as T and B cells) to target and eliminate specific pathogens. While adaptive immunity can indirectly contribute to inflammation by recruiting immune cells to the site of infection, it is not the primary cause of inflammation.Rate this question:
