4. The Loop of Henle Function:  Re-absorb into body Water and Na+ from the fluid being filtered (becomes urine)  This affects urine concentration.

5. De Descending Loop Permeable to Water Not permeable to Na+ Concentration of liquid Increases as Water exits Ascending Loop Permeable to Na+ Not permeable to Water Concentration of liquid Decreases as Na+ exits Water Na+ Loop of Henle
