Webreabsorption increases. Because aldosterone is also acting to increase sodium reabsorption, the net effect is retention of fluid that is roughly the same osmolarity as bodily fluids. The net effect on urine excretion is a decrease in the amount of urine excreted, with lower osmolarity than in the previous example.
