MICROANATOMY

Detailed explanation-1: -The monocyte, an agranular leukocyte, differentiates into a macrophage that then phagocytizes the pathogens.

Detailed explanation-2: -Monocytes are a type of phagocyte found in the bloodstream. They circulate around the body, and when a tissue is infected or inflamed they may leave the bloodstream and enter the tissue. In the tissue they differentiate into macrophages, which form the major resident population of phagocytes in normal tissues.

Detailed explanation-3: -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-4: -Monocytes differentiate into large phagocytic cells called macrophages.
