Introduction Neutrophils are important components of the human immune system, which play a key role in protecting the body from various infections and diseases. These cells surround and destroy pathogenic bacteria, viruses and other microorganisms that can cause disease. A neutrophil cell or neutrophilocyte is a type of granulocyte, one of the representatives of which is a motile, amoeboid bacteriophagocytic cell. Among the dead pathogenic organisms, fragments suitable for feeding lymphocytes are isolated. Unlike most leukocytes, they do not form standard clusters, but are scattered along the periphery of inflammation. It is no coincidence that the density of these cells in the site of inflammation can significantly exceed their density in the bone marrow. Due to their small size and mobility, neutrophil cells are called microphages. There are both polymorphonuclear (among which segmented or neutrophil segments predominate - they make up 4/5 of the total number of neutrophils) and monomorphonuclear (these are mature neutrophils). They are designated as segmented depending on the shape of the nucleus. The adult human body contains 1.5-3x109 immature granuloma cells, i.e. neutrophil precursors. Segmented neutrophils - 3.0–8.0 x1012 cells/l, among them 1–2% of cells are actively dividing

Neutrophils are the most common type of white blood cell in the human body. It is one of the earliest and most prominent molecule forms in the reticuloendothelial systems or lymphoid system. The functional role of these cells is related to inflammation and immune response. There are three main types of neutronphils - neutrophil lymphocytes, polymorphonuclear neutrophils and monocytes.
