Question

Which of the following would help in the prevention of diuresis?

• A. Atrial natriuretic factor causes vasoconstriction
• B. Decrease in the secretion of renin by JG cells
• C. More water reabsorption due to under secretion of ADH
• D. Reabsorption of Na+ and water from renal tubules due to aldosterone

Answer 1

The correct option is D

Reabsorption of Na+ and water from renal tubules due to aldosterone

The correct option is D

Explanation for the correct option:

1. When the kidneys filter too much body fluid, the condition is called diuresis.
2. As a result, body produce more urine and one need to use the restroom more frequently.
3. The normal adult will urinate four to six times each day, producing between three cups and three quarts of urine on average.
4. Aldosterone-induced renal tubule reabsorption of Na+ and water prevents diuresis.

Final answer: Reabsorption of Na+ and water from renal tubules due to aldosterone would help in the prevention of diuresis.
