Question
Regarding sodium reabsorption, which one of the following statements in INCORRECT?Group of answer choicesAlways occurs in the descending limb of the loop of Henle.It plays a role in the reabsorption of glucose and amino acids in the proximal tubule.It is under hormonal control in the distal tubule and collecting duct.In the loop of Henle sodium reabsorption contributes to the formation of a concentrated urine.
Solution
The incorrect statement is: "Always occurs in the descending limb of the loop of Henle."
Sodium reabsorption does not always occur in the descending limb of the loop of Henle. In fact, the descending limb is relatively impermeable to sodium, so very little sodium reabsorption occurs here. Most of the sodium reabsorption occurs in the ascending limb of the loop of Henle, the distal convoluted tubule, and the proximal convoluted tubule.
