Increase in sodium reabsorption in the distal convoluted tubule is caused by:
Correct answer: A. Increase in aldosterone levels
- A. Increase in aldosterone levels
- B. Increase in ADH levels
- C. Decrease in aldosterone levels
- D. Decrease in ADH levels
Explanation
Aldosterone enhances sodium reabsorption via sodium channels and Na⁺/K⁺ pumps.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
