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.
Leukocytes, or white cells, are responsible for the defense of the organism. In the blood, they are much less numerous than red cells. The density of the leukocytes in the blood is 5000-7000 /mm3. Leukocytes divide in two categories: granulocytes and lymphoid cells or agranulocytes. The term granulocyte is due to the presence of granules in the cytoplasm of these cells.
