Select the correct statement

Options

A. The juxta medullary nephrons have reduced Henle's loop
B. Vase recta is well developed in cortical nephrons
C. The PCT and DCT are situated in the medulla of the kidney
D. The ascending linb of the Henle's loop is connected to DCT

Answer

To solve the question "Select the correct statement," we need to analyze the statements related to the nephron's structure and function. Here’s a step-by-step breakdown:

### Step 1: Understand the Structure of Nephron
- The nephron is the functional unit of the kidney, consisting of various parts: Bowman's capsule, proximal convoluted tubule (PCT), loop of Henle, and distal convoluted tubule (DCT).
- The nephron can be classified into two types: cortical nephrons and juxtamedullary nephrons.

### Step 2: Identify the Location of Nephron Parts
- The PCT, DCT, and Bowman's capsule are located in the cortex of the kidney.
- The loop of Henle extends into the medulla, with its length varying between the two types of nephrons.

### Step 3: Analyze the Statements
1. **Juxtamedullary nephrons have reduced Henle's loop.**
- This is incorrect; juxtamedullary nephrons have a long loop of Henle.

2. **Vasa recta is well developed in cortical nephrons.**
- This is incorrect; vasa recta is well developed in juxtamedullary nephrons.

3. **The PCT and DCT are situated in the cortex of the kidney.**
- This statement is correct; both PCT and DCT are located in the cortex.

4. **The ascending limb of Henle's loop is connected to DCT.**
- This statement is also correct; the ascending limb of the loop of Henle leads into the DCT.

### Step 4: Select the Correct Statement
- Among the statements analyzed, the correct statement is: **"The PCT and DCT are situated in the cortex of the kidney."**

### Final Answer
The correct statement is: **"The PCT and DCT are situated in the cortex of the kidney."**
