Question
Which of the following about sodium reabsorption is INCOORRECT: Group of answer choices99% of sodium in the filtrate is reabsorbedMost of sodium reabsorption happens at the proximal tubulesSodium reabsorption increases when aldosterone levels elevatedMost of the sodium reabsorption occurs in the distal convoluted tubule
Solution
The incorrect statement about sodium reabsorption is: "Most of the sodium reabsorption occurs in the distal convoluted tubule."
Here's why:
-
"99% of sodium in the filtrate is reabsorbed" - This is correct. The kidneys filter out a large amount of sodium, but they also reabsorb most of it back into the bloodstream.
-
"Most of sodium reabsorption happens at the proximal tubules" - This is also correct. About 65% of sodium reabsorption occurs in the proximal tubules.
-
"Sodium reabsorption increases when aldosterone levels elevated" - This is correct. Aldosterone is a hormone that promotes sodium reabsorption in the kidneys.
-
"Most of the sodium reabsorption occurs in the distal convoluted tubule" - This is incorrect. While some sodium reabsorption does occur in the distal convoluted tubule, it's not where most of it happens. As mentioned earlier, the majority of sodium reabsorption occurs in the proximal tubules
