Solution
Correct Answer:
A
- Anatomy of the Loop: The Henle's loop is a U-shaped portion of the nephron.
- Descending Limb (A): This is the first part of the loop that dips into the renal medulla. It is permeable to water but almost impermeable to electrolytes.
- Ascending Limb (B): This part carries the filtrate back towards the cortex. It is impermeable to water but allows the transport of electrolytes.
- Conclusion: In the diagram provided, 'A' identifies the descending limb.
