The maintenance of normal volume and composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved
Three types of homeostasis are involved: fluid balance, electrolyte balance, and acid-base balance. Fluid balance means that the total quantity of body water remains almost constant and that the distribution between the ICF and ECF are normal. Electrolyte balance implies the same thing for ions. Acid-base balance means that the pH of the ECF is maintained in the range of 7.35 to 7.45, and that gains or losses of hydrogen ion as a consequence of metabolism are followed by equivalent losses or gains so as to maintain constant buffer reserves.
