- 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%
Thus,
| Na+ | H2O | |
| PCT | 65% | 65% |
| DLOH | 0 | 10% |
| ALOH | 25% | 0 |
| DCT | 5% | 0 |
| CD | 4-5% | 5-25% |
