The Blood The blood consists of cells and cell  fragments, called formed elements, and  water with dissolved molecules, called  blood plasma (see Table 1). Table 1. Formed Elements and Plasma of Blood Constituent Characteristics/Functions Formed Elements (45%) Erythrocytes (red blood cells) (98– 99%) anucleate, contain hemoglobin; O 2 and CO 2 transport Leukocytes (white blood cells)(0.1–0.3%): Neutrophils (60–70%) Eosinophils (2–4%) Basophils (0.5–1%) Lymphocytes (20–25%) Monocytes (3–8%) granulocytes, polymorphonuclear; phagocytosis, wound healing granulocytes, bilobed nucleus; phagocytosis granulocytes, 2 to 5 lobed nucleus; release histamine agranulocytes, circular nucleus, T cells, B cells; immune response, antibodies agranulocytes, large kidney-shaped nucleus; phagocytic macrophages Thrombocytes (platelets) (1–2%) anucleate, megakaryocyte fragments; blood clotting
