MICROANATOMY

Detailed explanation-1: –Neutrophils are phagocytes which ingest microorganisms or particles by the process called as antibody opsonization.-Thus, phagocytosis by neutrophils and monocytes is a key process in innate immune response. The most active phagocytes are Neutrophils and Monocytes.

Detailed explanation-2: -The neutrophil is the major phagocyte of the innate immunity and plays a key role in the host defense against staphylococcal infections.

Detailed explanation-3: -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-4: -There are three main groups of phagocytes: monocytes and macrophages, granulocytes, and dendritic cells, all of which have a slightly different function in the body.

Detailed explanation-5: -Neutrophils provide the first line of defense of the innate immune system by phagocytosing, killing, and digesting bacteria and fungi.
