Quizplus · Accepted Answer

Neutrophils and monocytes are the most active phagocytic cells in circulating blood. Neutrophils are the first cells to respond to an infection and are highly adept at phagocytosis. Monocytes are produced in the bone marrow and develop into macrophages when they enter tissues. Both neutrophils and monocytes are leukocytes (white blood cells) and play a critical role in the innate immune response.
