Which of the following causes an increase in sodium reabsorption in the distal convoluted tubule? (NEET-2014) a. Decrease in antidiuretic hormone levels b. Increase in aldosterone levels c. Increase in antidiuretic hormone levels d. Decrease in aldosterone levels
Option B. Aldosterone is secreted from the adrenal cortex. The main function of aldosterone is to serve as a stimulant of the renal absorption of sodium ions and water. This leads to the increment of the blood volume. When the aldosterone level is reduced, it helps to increase the sodium secretion by Distal Convoluted Tubules.
