A phagocyte engulfs a bacterium. Which type of immune response is this?
Answer and explanation
Correct answer: D. Non-specific, an innate response
- Step 1: Phagocytes engulf and digest pathogens.
- Step 2: This response is the same for all pathogens, so it is non-specific.
Answer
Non-specific, an innate response.
Why not the others: Specific, an adaptive response: phagocytosis does not target one pathogen type. Passive immunity: this is acquired from another source. Active immunity from a vaccine: no vaccine is involved.
