Detailed explanation-1: -Out of the WBCs, there are only three that are phagocytic namely neutrophils, monocytes, and eosinophils. Eosinophil cells fight allergic and parasitic infections. Out of these three, neutrophils and monocytes are the most active phagocytic cells.
Detailed explanation-2: -Monocytes can phagocytose and present antigens, secrete chemokines, and proliferate in response to infection and injury. Once recruited to tissues, monocytes are capable of differentiating into macrophages and dendritic cells.
Detailed explanation-3: -Neutrophils are the most abundant white blood cell in humans and arise from granulocytes. They are also phagocytic in nature, and Metchnikoff called neutrophils the “archetypal phagocyte”. Neutrophils are the first immune cells to be recruited, which can be through the cytokines produced by macrophages.
