Final answer:
Fever is the process not involved in phagocytosis, which includes steps like chemotaxis, adherence, ingestion, and killing of pathogens by phagocytes. The correct option is E.
Step-by-step explanation:
The process not involved in phagocytosis is fever. Phagocytosis is an immune response which involves several key steps: chemotaxis, which is the movement of phagocytes toward infection sites; adherence, where the phagocyte bonds to the pathogen; ingestion, where the pathogen is engulfed by the phagocyte; and killing, where the engulfed pathogen is destroyed within the phagolysosomes of the phagocyte.
Fever is a systemic response to infection and is not a direct part of the phagocytic process.
