Step 1: Understanding phagocytosis.
Phagocytosis is the process of engulfing and digesting pathogens. Step 2: Phagocytic WBCs.
Neutrophils and monocytes are the primary phagocytic white blood cells. Step 3: Non-phagocytic cells.
Eosinophils are mainly involved in allergic responses and parasitic infections.
Basophils release histamine and heparin but do not perform phagocytosis. Step 4: Conclusion.
Therefore, eosinophils and basophils are non-phagocytic.
