White blood cells (also called leukocytes) come in five main varieties:
- Basophils, which release histamine and other chemicals to promote blood flow to an area of infection or other immune response
- Eosinophils, cells that release powerful chemicals that serve to rapidly mediate asthma and allergy attacks
- Lymphocytes, which produce antibodies that attack bacteria and viruses—and even destroy cancer cells

The most common type of white blood cell is the neutrophil, which is the "immediate response" cell and accounts for 55 to 70 percent of the total white blood cell count. Each neutrophil lives less than a day, so your bone marrow must constantly make new neutrophils to maintain protection against infection.
