Consider this situation: you want to reabsorb sodium ions but you do not want to increase the volume of the blood by reabsorbing
choli [55]

Answer:

Increase aldosterone and decrease ADH

Explanation:

Aldosterone causes reabsorption of sodium ions while Antidiuretic hormone (ADH) causes reabsorption of water. Aldosterone also causes water reabsorption due to increased osmotic pressure by reabsorbing sodium ions. But for water reabsorption, Aldosterone has to work along with ADH to increase permeability for water. If we increase Aldosterone and decrease ADH, the sodium ions will be reabsorbed while water cannot be reabsorbed due to decreased permeability of DCT and collecting tubules for water.
