Unlike regular red blood cells, white blood cells have nuclei, mitochondria, and all other normal cellular structures. Lymphocytes, which are further divided into B cells and T cells, are responsible for the specific recognition of foreign agents and their subsequent removal from the host. However, as cells of the innate immune system, NK cells are classified as group I Innate Lymphocytes (ILCs) and respond quickly to a wide variety of pathological challenges. White cells are highly differentiated for their specialized functions, and they do not undergo cell division ( mitosis) in the bloodstream; however, some retain the capability of mitosis. They may also be low due to nutritional imbalances, chemotherapy and radiation treatments, autoimmune disorders, and some infections.
