Options

A. Shorteer
B. Longer
C. Of same size
D. Unecrtain

Answer

To answer the question, "In comparison to the cortical nephrons, Henle's loop of juxtamedullary nephrons is:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Nephrons**:
- Nephrons are the functional units of the kidney, consisting of a glomerulus and a renal tubule. The renal tubule includes the proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), and collecting duct (CD).

2. **Identify the Types of Nephrons**:
- There are two main types of nephrons: cortical nephrons and juxtamedullary nephrons.
- Cortical nephrons have a shorter loop of Henle that extends only slightly into the medulla.
- Juxtamedullary nephrons have a longer loop of Henle that extends deep into the medulla.

3. **Compare the Loops of Henle**:
- The loop of Henle in cortical nephrons is relatively short.
- In contrast, the loop of Henle in juxtamedullary nephrons is significantly longer.

4. **Conclusion**:
- Therefore, in comparison to the cortical nephrons, the Henle's loop of juxtamedullary nephrons is longer.

### Final Answer:
The Henle's loop of juxtamedullary nephrons is **longer** compared to that of cortical nephrons.
