Select the correct statement

Options

A. the ascending limb of the Henle's loop extends as the DCT
B. the Juxtamedullary nephrons have reduced Henle's loop
C. vasa recta is well developed in cortical nephrons
D. the glomerulus encloses the Bowman's capsule

Answer

To solve the question "Select the correct statement," we will analyze the provided statements about the nephron and its components, particularly focusing on the loop of Henle and the distal convoluted tubule (DCT).

### Step-by-Step Solution:

1. **Understanding the Nephron Structure**:
- The nephron is the functional unit of the kidney, consisting of several parts including the glomerulus, Bowman’s capsule, proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), and collecting ducts.

2. **Identifying the Components of the Loop of Henle**:
- The loop of Henle consists of two limbs: the descending limb and the ascending limb.
- The descending limb is responsible for the reabsorption of water, while the ascending limb is involved in the reabsorption of ions.

3. **Analyzing the Statement**:
- The statement in question is: "The ascending limb of the Henle loop extends as the DCT."
- According to the structure of the nephron, after the loop of Henle, the ascending limb leads directly into the distal convoluted tubule (DCT).

4. **Verifying the Correctness of the Statement**:
- Since the ascending limb of the loop of Henle does indeed extend into the DCT, this statement is correct.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the first statement is true.

### Final Answer:
The correct statement is: "The ascending limb of the Henle loop extends as the DCT."
