Step 1
Step 2
Step 3
A decrease in glucose moving from the renal tubule into capillaries
Answer
The movement of glucose primarily occurs through co-transport mechanisms in the proximal tubule, and its reabsorption does not directly relate to water absorption in the collecting tubule. Hence, this option does not result in increased water absorption.
Step 4
An increase in the concentration of dialysate solution in renal dialysis
Answer
This option pertains to the process of dialysis, where increased concentration gradients can enhance the removal of waste products but does not directly affect water absorption in the nephron. Therefore, it is not the correct answer.
