Solution
Correct Answer:
Concentration of urine
- Urine Concentration: Terrestrial animals need to conserve water by producing concentrated urine.
- Key Structures: The Henle's loop and the vasa recta work together in the renal medulla.
- Mechanism: They create an osmolarity gradient (Counter Current Mechanism) that allows for the passive reabsorption of water from collecting ducts.
- Conclusion: These structures play a significant role in the concentration of urine.
