Which of the following cells of the immune system do not perform phagocytosis?

  • A.Macrophage
  • B.Neutrophil
  • C.Eosinophil
  • D.Basophil

Answer: D

Correct answer: Basophil

Basophils do not phagocytose. They are the circulating counterparts of mast cells: they carry granules of histamine and heparin and release them, driving inflammation and allergic reactions. Macrophages and neutrophils are the principal phagocytes, and eosinophils will engulf antigen-antibody complexes as well as attacking parasites.
