- ANF acts on the kidney to increase Na+ excretion and GFR also inhibit rennin secretion.
- Due to decrease in secretion of renin, it reduced concentration of angiotensin I & II.
- ADH stimulates water reabsorption by stimulating insertion of water channels or aquaporins into the membranes of kidney tubules.
- Reabsorption of Na+ and water from renal tubules due to aldosterone help in prevention of diuresis.

Prevention of Diuresis
Diuresis refers to the increased production of urine by the kidneys, resulting in increased urine volume. To prevent diuresis, several mechanisms come into play to regulate water and sodium reabsorption in the kidneys. Among the given options, option D, which involves the reabsorption of sodium (Na+) and water from renal tubules due to aldosterone, is the correct answer.
Aldosterone and Reabsorption
Aldosterone is a hormone produced by the adrenal glands. Its primary function is to regulate the reabsorption of sodium ions and water in the distal tubules and collecting ducts of the kidneys. This hormone acts on the cells lining these tubules and ducts, promoting the reabsorption of sodium ions and the secretion of potassium ions.
How Aldosterone Prevents Diuresis
When aldosterone is released, it binds to specific receptors on the cells of the distal tubules and collecting ducts. This binding triggers several cellular processes that result in increased sodium reabsorption and water reabsorption. This prevents excessive loss of sodium and water in the urine, thus preventing diuresis.
Effects of Aldosterone
- Increased Sodium Reabsorption: Aldosterone increases the activity of sodium-potassium pumps in the cells lining the tubules and ducts. These pumps actively transport sodium out of the tubular fluid and into the cells, creating a concentration gradient that favors the movement of sodium into the blood. This process helps to retain sodium in the body, preventing excessive loss in the urine.
- Water Reabsorption: As sodium is reabsorbed, water follows passively due to osmosis. This leads to increased water reabsorption from the tubular fluid into the blood, preventing diuresis.
Conclusion
In summary, the reabsorption of sodium and water from renal tubules due to aldosterone plays a crucial role in preventing diuresis. Aldosterone promotes the reabsorption of sodium and the subsequent osmotic reabsorption of water, ultimately leading to the conservation of sodium and water in the body.
