Question

The relationship between the ascending and descending limbs of the loop of henle in juxtamedullary nephrons provides the ___?

- Mechanism by which we reabsorb glucose in the proximal tubule

- Countercurrent multiplier

- Mechanisms for water reabsorption in the proximal and distal tubule

Answer 1

Answer

The relationship between the ascending and descending limbs of the loop of henle in juxtamedullary nephrons provides the : Countercurrent multiplier

• Descending limb is permable to water and impermeable to the salts.
• Ascending limb is permable to salts and impermeable to the water.
• When the filtrate passes through loop of Henle, the osmotic gradient between tubular fluid and interstitial space is increased.
• This aids in water reabsoprtion for production of concentrated urine.
