Production of red blood cells ( erythropoiesis) Red cells are produced continuously in the marrow of certain bones. 2022]. Unlike regular red blood cells, white blood cells have nuclei, mitochondria, and all other normal cellular structures. They engulf bacteria and cellular debris by phagocytosis and release the enzyme lysozyme, which destroys some bacteria.

There are several different types with different purposes. The body contains five types of granulocytes these are white blood cells that contain cell-specific granules. White blood cells are a very important part of this system. T lymphocytes directly attack and destroy pathogens (bacteria and viruses), and B lymphocytes develop into antibody-producing plasma cells in response to foreign antigens. That's because when your body needs extra help against pathogens, it makes more white blood cells. Inherited defects of the migratory process also lead to susceptibility to infection. A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production. We have already looked at white blood cell morphology and been introduced to the basic types.
