Orchestrating allergic responses, they are believed to play a part in protectingīecause they have densely staining granules in their cytoplasm they are also Reside near small blood vessels and, when activated, release substances thatĪffect vascular permeability. Precursors are not well defined, also differentiate in the tissues. Upon encountering a pathogen, they rapidly mature and Phagocytic and macropinocytic, ingesting large amounts of the surroundingĮxtracellular fluid. Immatureĭendritic cells migrate from the blood to reside in the tissues and are both Take up antigen and display it for recognition by lymphocytes. ![]() They are the mature form of monocytes, which circulate in the blood and differentiateĬontinuously into macrophages upon migration into the tissues. ![]() Widely in the body tissues, where they play a critical part in innate immunity. ![]() MacrophagesĪre one of the three types of phagocyte in the immune system and are distributed ![]() Macrophages, dendritic cells, and mast cells of the immune system. The myeloid progenitor is the precursor of the granulocytes, These pluripotent cells divide to produce two more specialized types The adaptive immune system, arise from hematopoietic stem cells in All the cellular elements of blood, including the lymphocytes of
