Document Summary

Erythrocytes: red blood cells, transport o2+co2. Leukocytes: white blood cells, defend body against pathogens. Platelets: cell fragments formed from megakaryocyte, form blood clots. Water: solvent for carrying other substances, absorb heat. Ions: salts (na, k, ca, mg, cl, bicarbonate, osmotic balance, ph buffering, regulation of membrane permeability, blood needs concentration of 300 mosm/l of water. Organic molecules: glucose, amino acids, proteins, albumins, osmotic balance, ph buffering, problems with albumins cause kwashiorkor syndrome, globulins, defense (antibodies, lipid transport, fibrinogen, clotting of blood, lipids, nitrogenous waste. Never let monkeys eat bananas= leukocytes in order from most common->least common. Color: bright red=o2 rich, dark red= o2 poor, blood is never blue. Ph of 7. 35-7. 45 (too low=acidosis too high= alkalosis temperature of 100. 4 f to circulate heat. Increase osmotic pressure, buffer h+, blood viscosity, provide fuel during starvation. 3 classes of plasma proteins: albumins, carriers, globulins, carriers, clotting factors, precursor protein-> angiotensin, immunoglobulins, fibrinogen, blood clotting. Nutrients: glucose, amino acids, lipids, vitamins.
