When aldosterone is absent, Na+ reabsorption in the nephron is greatly reduced, and as 30-40g of sodium can be lost in the urine daily. The answer is decreased. Site: Anatomy and Physiology Eighth Edition by Seeley Stephens Tate.
Aldosterone enhances sodium reabsorption, which increases water reabsorption into the blood from the collecting tubules. Because of the effect of aldosterone on the collecting tubules, the amount of water excreted in the urine decreases and blood volume and blood pressure increase. Endocrine cells in the kidneys produce the hormone erythropoietin, which controls erythrocyte production.
