Which cell is the most potent phagocytic cell in the tissue?

• A. Neutrophil
• B. Dendritic cell
• C. Eosinophil
• D. Basophil

Answer: (B)

Phagocytosis is most efficient in neutrophils, which are the rapid, highly phagocytic first responders at infection sites in tissues. They flood into tissues, engulf many microbes quickly, and release potent antimicrobial compounds in their granules, making them exceptionally effective at rapid pathogen clearance. Dendritic cells do perform phagocytosis to sample antigens, but their primary role is to process those antigens and present them to T cells to kick off adaptive immunity. Their phagocytic activity is not as strong as that of neutrophils (or macrophages) when it comes to immediate microbial killing. Eosinophils and basophils have limited phagocytic activity and specialize more in defense against parasites and in mediating allergic/inflammatory responses, rather than being the main phagocytes in tissue. So, the cell best known for potent phagocytosis in tissue is the neutrophil.
