Final answer:
Neutrophils employ phagocytosis, release of antimicrobial substances, and formation of neutrophil extracellular traps (NETs) to eliminate microbes.
Step-by-step explanation:
Neutrophils employ multiple mechanisms to eliminate microbes, including:
- Phagocytosis: Neutrophils engulf and ingest the microbes, resulting in their death and removal from the body.
- Release of antimicrobial substances: Neutrophils release chemicals that destroy pathogens and prevent them from harming human cells.
- Formation of neutrophil extracellular traps (NETs): Neutrophils can also create NETs, which are web-like structures composed of DNA and antimicrobial proteins that trap and kill microbes.
Therefore, the correct answer is d) All of the above.
