Which of the following would help in prevention of diuresis?

  1. A
    More water reabsorption due to undersecretion of ADH
  2. B
    Reabsorption of and water from renal tubules due to aldosterone
  3. C
    Atrial natriuretic factor causes vasoconstriction
  4. D
    Decrease in secretion of renin by JG cells

Solution & Step-by-step Explanation

Aldosterone causes reabsorption of and water from the distal parts of the tubule. This increases blood volume and pressure, thereby preventing diuresis (excessive urination).Undersecretion of ADH causes diuresis.ANF is a vasodilator.Renin decrease would lower blood pressure.
