Objectives Explain how the ph of the blood is stabilized by bicarb buffer and define the terms acidosis and alkalosis Explain how the acid-base balance of the blood is affected by co, and Hco and describe the roles of the lungs and kidneys in maintaining acid-base balance Explain how CO, affects blood pH, and hypoventilation and hyperventilation affect acid-base balance Explain how the interaction between plasma K+ and h concentrations affects the tubular secretion of theseObjectives ◼ Explain how the pH of the blood is stabilized by bicarb buffer and define the terms acidosis and alkalosis. ◼ Explain how the acid-base balance of the blood is affected by CO2 and HCO3 - , and describe the roles of the lungs and kidneys in maintaining acid-base balance. ◼ Explain how CO2 affects blood pH, and hypoventilation and hyperventilation affect acid-base balance. ◼ Explain how the interaction between plasma K+ and H+ concentrations affects the tubular secretion of these
