Loop of henle come deep into medulla in

Answer

To solve the question "Loop of Henle comes deep into medulla in," we can follow these steps:

### Step-by-Step Solution:

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

2. **Identify the Loop of Henle**:
- The loop of Henle is a U-shaped structure that connects the PCT and DCT. It plays a crucial role in the concentration of urine.

3. **Differentiate Between Types of Nephrons**:
- There are two main types of nephrons: cortical nephrons and medullary nephrons.
- Cortical nephrons have shorter loops of Henle that do not extend deeply into the medulla.
- Medullary nephrons, on the other hand, have long loops of Henle that extend deep into the medulla of the kidney.

4. **Conclude the Answer**:
- Since the question asks about the loop of Henle coming deep into the medulla, the answer is that this occurs in **medullary nephrons**.

### Final Answer:
The loop of Henle comes deep into the medulla in **medullary nephrons**.
