Which of the following cells do not exhibit phagocytotic activity? (a) Monocytes                  (b) Neutrophil                   (c) Basophil                         (d) Macrophage

Answer:

                (c) Basophil are least common of granulocyte, only composed of 0.01% to 0.3% of the circulating white blood cells. These are involved in specific kinds of inflammatory reactions, particularly those which cause allergic reactions and do not exhibit phagocytotic activity. Whereas, monocytes migrate from blood stream to tissue and differentiate into resident macrophage, e.g., kupffer cells in liver and neutrophils target bacteria and fungi. Mecrophages are also phagocytotic in nature.
