Question: 1 / 1820

What happens in the Loop of Henle?

Only Na reabsorption

Only K reabsorption

Water and Na reabsorption, affected by ADH

The Loop of Henle is a section of the nephron in the kidney that plays a significant role in filtering and reabsorbing substances from the blood. Option A and B are incorrect because in the Loop of Henle, Na and K reabsorption both occur, not just one or the other. Option D is incorrect because Ca reabsorption mainly occurs in the distal convoluted tubule, not the Loop of Henle. Option C, on the other hand, is the correct answer because not only does the Loop of Henle reabsorb Na and water, but it is also affected by the hormone ADH (antidiuretic hormone) which controls the amount of water that is reabsorbed back into the body. This allows for the body to maintain proper hydration levels.
