Final answer:
Eosinophils are highly phagocytic for antigen-antibody complexes. They release antihistamines to counteract inflammation caused by histamines, and their granules contain molecules toxic to parasitic worms.
Step-by-step explanation:
Eosinophils are a type of white blood cell that is involved in the immune response, particularly in allergic reactions and defense against parasitic infections. They release antihistamines to counteract inflammation caused by histamines, and their granules contain molecules toxic to parasitic worms.
Eosinophils are capable of phagocytosis, which is the process of engulfing and digesting pathogens. They are particularly effective when antibodies bind to the target and form an antigen-antibody complex. Therefore, eosinophils are highly phagocytic for antigen-antibody complexes.
