They patrol through our bloodstream in search of harmful pathogens, which are any harmful threat in the body. Suicidal NETosis and vital (or classical) NETosis are forms of programmed cell death. On the basis of their appearance under a light microscope, white cells are grouped into three major classeslymphocytes, granulocytes, and monocyteseach of which carries out somewhat different functions. The T cells destroy the body's own cells that have themselves been taken over by viruses or become cancerous. White blood cells are are also known as leukocytes . They can produce antitoxins - antitoxins counteract the toxins that invading bacteria may produce. These cells contain many cytoplasmic granules, or secretory vesicles, that harbour potent chemicals important in immune responses. White blood cells are also called leukocytes. They have a large, single nucleus that comes in a variety of shapes but is most often kidney-shaped. They are characterised by the multi-lobed shape of their nucleus (Figure 1, left) which distinguished them from other white blood cells of lymphoid or myeloid origin, such as lymphocytes and monocytes. Alveoli in the human lung. Inherited defects of the migratory process also lead to susceptibility to infection. Neutrophils are the most abundant white blood cell in circulation. (The others are plasma, platelets and white blood cells.) I feel like its a lifeline. Leukocytes (also called white blood cells) are a cellular component of the blood that lacks hemoglobin, has a nucleus and is capable of motility, They defend the body against infection and disease by: ingesting foreign materials and cellular debris; by destroying infectious agents and cancer cells; or by producing antibodies[1]. We now know that lymphoid and myeloid progenitors cross over. It now seems that eosinophils might even play a role in glucose homeostasis. They also destroy parasitic worms and phagocytize antigen- antibody complexes. Red blood cells cannot divide or replicate like other bodily cells.
