Aldosterone from adrenal cortex stimulates the reabsorption of water and Na ^+ from ______.

Step-by-step solution

Aldosterone is a mineralocorticoid hormone secreted by the adrenal cortex. It acts mainly on the distal parts of the nephron, specifically the Distal Convoluted Tubule (DCT) and the collecting duct. It stimulates the conditional reabsorption of Na ^+ and water from the filtrate in the DCT, which helps in maintaining the blood pressure, blood volume, and osmotic balance. It also stimulates the excretion of K ^+ and phosphate ions. Answer: Distal Convoluted Tubule (DCT)
