- Both limbs
What is the role of the ascending limb of the loop of Henle?
What is the role of the ascending limb of the loop of Henle?
- Maintenance of high osmolarity (correct)
- Reabsorption of water
- Dilution of filtrate
- Reabsorption of electrolytes
What happens to the filtrate as it moves down the loop of Henle?
What happens to the filtrate as it moves down the loop of Henle?
- It gets concentrated (correct)

Flashcards
Descending Limb of the Loop of Henle
Descending Limb of the Loop of Henle
This part of the loop of Henle allows water to pass through its membrane but not electrolytes. This contributes to the concentration of the urine.
Ascending Limb of the Loop of Henle
Ascending Limb of the Loop of Henle
This part of the loop of Henle actively pumps out electrolytes, which contributes to the concentration of the urine.
Filtrate Concentration
Filtrate Concentration
As the filtrate moves down the loop of Henle, water is reabsorbed, making the urine more concentrated.
