Question
The major importance of regulating ECF osmolarity is
to prevent spontaneous depolarization of nerve and muscle cell membranes because of shifts in Na+ balance
to prevent the urine from becoming too concentrated
to prevent an acid-base imbalance if the hydrogen ions were to become too concentrated or too dilute in the body fluids
to prevent fluid shifts between cells and the ECF, which could produce profound symptoms as the cells swell or shrink
to help maintain blood pressure
