The blood has several types of white blood cells including neutrophils, bands, eosinophils, basophils, monocytes and lymphocytes. Each fights infection in a different way. Neutrophils, for example, are one of the body's main defenses against bacteria. Neutrophils kill bacteria by ingesting them. Neutrophils can ingest five to 20 bacteria in their lifetime. Another type of white blood cell is called bands. Bands are immature neutrophils.

Another type of white blood cell is called bands.Bands are immature neutrophils. When a bacterial infection is present, an increase of both neutrophils and bands are seen. The eosinophil type of white blood cell kills parasites and has a role in allergic reactions.asophils release histamine (which makes blood vessels leak and attracts white blood cells) and heparin (which prevents clotting in an infected area so that the white blood cells can reach the bacteria). Monocytes enter the tissue itself, where they become larger. There they can ingest bacteria throughout the body.
