The descending limb of the loop of Henle is:
Show answer and explanation
Correct answer: Permeable to water but almost impermeable to electrolytes
The descending limb allows water to pass out into the medullary fluid due to high osmotic pressure. Because it is impermeable to salts, the filtrate becomes concentrated as it moves down.

- Conditional reabsorption of Na+ and water takes place in which part of the nephron?
- Which of the following is NOT secreted into the filtrate in the PCT?
- Large amounts of water could be reabsorbed from this region to produce concentrated urine:
- Reabsorption of water in the renal tubules occurs via:
- The net filtration pressure (NFP) that causes ultrafiltration in the glomerulus is primarily determined by:
