Hormonal Regulation of Sodium Reabsorption in the Nephron

The kidneys play a pivotal role in maintaining the body's internal environment through the regulation of fluid and electrolyte balance. One of the key processes occurring in the nephron is the reabsorption of sodium ions. This process is essential for maintaining blood pressure and overall fluid balance. The regulation of sodium reabsorption is influenced by several hormones, including aldosterone. The relationship between aldosterone and sodium reabsorption is crucial for understanding renal function and its impact on blood pressure.

Which of the following hormones primarily stimulates the reabsorption of sodium in the distal convoluted tubule and the collecting duct of the nephron?
