3.12.6.2. Sodium and water resorption by segments
Sodium and water resorption by segments
[Ref: AV6: p75,p82-83]
Sodium reabsorption
- Proximal tubules = 65%
- Descending limb of loop of Henle = 0%
- Ascending limb of loop of Henle = 25%
* Thick AND thin
- Distal convoluted tubules = 5%
- Collecting duct system = 4-5%
Water reabsorption
- Proximal tubules = 65%
- Descending limb of LOH = 10%
- Ascending limb = 0%
* Thick AND thin
- Distal convoluted tubules = 0%
- Collecting duct system = 5-25%
