Which of the following is located in the medulla of the kidney?

Options

A. Malpighian body
B. PCT
C. Henle's loop
D. DCT

Answer

To determine which structure is located in the medulla of the kidney, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Kidney**: The kidney is divided into two main regions: the outer region called the cortex and the inner region known as the medulla.

2. **Identify the Components of the Kidney**: The kidney contains several structures, including:
- Malthusian body (also known as the renal corpuscle)
- Proximal Convoluted Tubule (PCT)
- Loop of Henle (Henle's loop)
- Distal Convoluted Tubule (DCT)

3. **Locate Each Component**:
- **Malthusian Body**: This structure is located in the cortex of the kidney.
- **Proximal Convoluted Tubule (PCT)**: This is also found in the cortex.
- **Loop of Henle (Henle's loop)**: This structure extends into the medulla of the kidney.
- **Distal Convoluted Tubule (DCT)**: This is located in the cortex.

4. **Conclusion**: Among the options provided, the only structure that is located in the medulla of the kidney is the **Loop of Henle**.

5. **Final Answer**: The correct answer is **Henle's loop**.
