question 55
phagocytes ______.
a all of these
b play a role in inflammation
c recognize, bind, and ingest pathogens
d trigger adaptive immune responses

Explanation:

To solve this, we analyze each option about phagocytes:

• Option B: Phagocytes (like neutrophils, macrophages) are part of the inflammatory response, so they play a role in inflammation.
• Option C: Phagocytes' main function is phagocytosis—recognizing, binding, and ingesting pathogens (like bacteria, debris).
• Option D: Phagocytes (e.g., dendritic cells) present antigens to trigger adaptive immune responses (like activating T - cells).

Since B, C, and D are all correct statements about phagocytes, "All of these" (Option A) is the right choice.

Answer:

A. All of these
