Renal System Discussion 2
Q 1.What ion serves at the driving force behind water reabsorption in the nephron?
2. 2. Explain how the distal tubule can vary its reabsorption of water and solutes.
1. The presence of sodium ions provides an osmotic force for the process of reabsorption in the neuron. The active reabsorption of sodium is the primary driving force for most renal absorption . Sodium ions is present in high concentration in the filtrate and it moves from tubule lumen into the proximal tubule epithelial and passes passively .
