ABSTRACT
Blood contains a number of cellular elements, including the erythrocytes (red blood cells), which contain the hemoglobin important for oxygen transport; the leukocytes (white blood cells); and thrombocytes (platelets); these cells circulate within the uid plasma. The term hemopoiesis or hematopoiesis is used to describe the formation of blood: hemo or hemato meaning “blood” and “poiesis” to make.
