Leukocytes (white blood cells). The WBCs are divided into two groups: (1) granular leukocytes, containing distinctive cytoplasmic granules, including neutrophils, eosinophils and basophils and (2) agranular leukocytes, without granules, including monocytes and lymphocytes.
White cells, or leukocytes, exist in variable numbers and types but make up a very small part of blood's volume--normally only about 1% in healthy people. Leukocytes are not limited to blood. They occur elsewhere in the body as well, most notably in the spleen, liver, and lymph glands.
