7 Plasma pH: 7.35 – 7.45 ➢Maintained in a very narrow range through numerous mechanisms. ➢Acids in the blood are buffered by bicarbonate in the plasma, and blood pH is maintained by the actions of the lungs and kidneys. ➢The lungs aid acid –base balance through elimination of carbon dioxide, which regulates the amount of carbonic acid in the blood. ➢The kidneys participate in acid – base balance by excreting H+ and retaining plasma bicarbonate

Red cells(Erythrocytes) Number: 5.1 to 5.8 million in males and 4.3 to 5.2 million in females per milliliter blood Shape: flat, biconcave discs. about 7 um in diameter and 2.2 um thick Importance of the unique shape: provides an increased surface area through which gas can diffuse
