Answer:
The correct answer is option B. Renal tubules increase excretion of potassium ions.
Explanation:
Aldosterone is a hormone released and produced by the cortex of the adrenal gland present above the kidneys. It increases the blood volume and blood pressure by reabsorbing the sodium ion along with water.
It is a hormone that has an impact on the ability to regulate blood pressure. It sends signals to the colon and kidney so these organs can increase the sodium ion reabsorb and increase the excretion of potassium ion.
Thus, the correct answer is option B. Renal tubules increase excretion of potassium ions.
