Unformatted text preview: 2. Why is Na reabsorption also controlled by feedback systems regulating atrial stretch and MAP? [Na] largely determines ECF fluid volume, which also determines blood pressure. 3. a. For what substances is tubular secretion the primary mechanism of homeostasis? Potassium ions, hydrogen ions and organic ions. b. What is the engineof tubular secretion? The Na/K ATPase c. What hormone most affects potassium secretion? Aldosterone 4. By what mechanisms in acid/base balance of the ECF maintained? Buffering systems in the plasma, control systems related to breathing, and the control system involving tubular secretion of H + and reabsorption of HCO3-...
