Function of blood: distribution of, o2 and nutrients, metabolic wastes and hormones, regulation of, body temp, ph and fluid volume, protection against, blood loss infection. Blood plasma: 90% water, proteins are mostly produced by liver, albumin, globulins, fibrinogen. Formed elements: wbcs are complete cells, rbcs have no nuclei or organelles, platelets are cell fragments, most formed elements survive in bloodstream for only a few days, most blood cells originate in bone marrow. Erythrocytes: biconcave discs, anucleate, no mitochondria, atp production is anaerobic filled with hemoglobin (hb) for gas transport, major factor contributing to blood viscosity.
