Explain the significance of sodium reabsorption across the different portion of the nephron
What will be an ideal response?
Sodium reabsorption in the proximal tubules plays a pivotal role in reabsorbing glucose, amino acids, electrolytes, and water. Sodium reabsorption in the ascending limb of the loop of Henle plays an important role in the kidney's ability to produce urine of varying concentrations. Sodium reabsorption in the distal tubules and collecting ducts is under hormonal control and plays a key role in regulating ECF volume and arterial blood pressure.
