Document Summary
Blood plasma and ph: acidosis: blood becomes to acidic (less than 7. 35, holding your breath, too much co2, alkalosis: blood becomes too basic (greater than 7. 45, hyperventilating, getting rid of the co2. In each scenario, the respiratory system and kidneys help restore blood ph to normal: carbon dioxide can dissolve in water (blood plasma) and form carbonic acid, forms an acid, releases hydrogen into the solution. Acid-base balance: normal ph of arterial blood = 7. 4. Iron is a component of hemoglobin: lost cells are replaced by division of hemocytoblasts in red bone marrow, normal hemoglobin content of blood, men = 13-18 g/dl, women = 12-16 g/dl. Anemia: decrease in the oxygen-carrying capacity of blood: dietary anemia. Iron: iron-deficiency anemia: pernicious: lack of vitamin b12, hemorrhagic anemia: bleeding, hemolytic anemia: malaria or sickle cell anemia, aplastic anemia: bone marrow defect, renal anemia: kidney disease, problems with erythropoietin production.
