About half the volume of normal blood is occupied by cells. By far the greater proportion of these cells are the erythrocytes, which contain hemoglobin and are responsible for the red color, and the principal function of which is oxygen transport. One or two per thousand cells in blood are colorless, and are known as white cells, or leukocytes. Stained blood smears show that there are six types of cells in blood besides the red cells. The appearances of these six types are illustrated in Figs. 1.1 and 1.2, and their relative proportions and absolute counts are given in Table 1.1.
