U shaped blood vassel

Options

A. Henles loop
B. Furcula
C. Vasa varicosa
D. Vasarecta

Answer

### Step-by-Step Solution:

1. **Understanding Nephrons**: Nephrons are the structural and functional units of the kidney. They play a crucial role in the filtration and excretion of waste products from the blood.

2. **Components of Nephrons**: Each nephron consists of two main parts:
- **Glomerulus**: A network of capillaries where blood filtration occurs.
- **Renal Tubule**: This is further divided into several segments:
- **Proximal Convoluted Tubule (PCT)**: The first segment where reabsorption of water, ions, and nutrients occurs.
- **Loop of Henle**: The U-shaped part of the renal tubule that consists of descending and ascending limbs.
- **Distal Convoluted Tubule (DCT)**: The segment following the Loop of Henle.
- **Collecting Duct**: The final segment where urine is collected.

3. **Identifying the U-shaped Blood Vessel**: The question specifically asks about a U-shaped blood vessel associated with the nephron. The blood vessels that run parallel to the Loop of Henle are known as the **Vasa Recta**.

4. **Conclusion**: Therefore, the U-shaped blood vessel that is associated with the Loop of Henle in the nephron is called the **Vasa Recta**.

### Final Answer:
The U-shaped blood vessel is called the **Vasa Recta**.
