Document Summary
19. 2 composition of blood (8% of body weight) Colloid liquid (cid:272)ontaining suspended su(cid:271)stan(cid:272)es that don"t settle out of a solution. Ions involved in osmosis, membrane potentials, and acid-base balance: nutrients glucose, amino acids, triacylglycerol, cholesterol, vitamins, waste products. Breakdown products of protein metabolism: urea, uric acid, creatinine, ammonia salts. End product of anaerobic respiration: lactic acid: gases oxygen, carbon dioxide, and inert nitrogen, regulatory substances hormones, enzymes. Red blood cells (erythrocytes) biconcave discs, anucleate, contain hemoglobin; Transports oxygen and carbon dioxide: white blood cells (leukocytes, granylocytes cytoplasm contains granules have multi-lobed nuclei. 3 distinctive types: neutrophils, eosinophils, basophils: agranulocytes cytoplasm contains small granules, nuclei are not lobed. Stem cells all formed elements derived from a single population (hemocytoblast) Proerythroblasts develop into red blood cells: myeloblasts develop into basophils, neutrophils, eosinophils (in white blood cells) Lymphoblasts develop into lymphocytes: monoblasts develop into monocytes, megakaryoblasts develop into platelets. Found in slightly higher concentration in male than in female plasma.
