Which forms glomerulus

Options

A. Efferent arteriole
B. Afferent arteriole
C. Uriniferous tubule
D. Vasa recta

Answer

To answer the question "Which forms glomerulus?", we will analyze the options provided and determine which one is correct.

### Step-by-Step Solution:

1. **Understanding the Glomerulus**: The glomerulus is a network of tiny blood vessels (capillaries) located in the nephron of the kidney. Its primary function is to filter blood and form urine.

2. **Evaluating the Options**:
- **Option 1: Efferent Arteriole**: This option is incorrect. The efferent arteriole carries blood away from the glomerulus and is involved in forming the peritubular capillary network, not the glomerulus itself.

- **Option 2: Afferent Arteriole**: This option is correct. The afferent arteriole supplies blood to the glomerulus. It is the entry point for blood into the glomerulus, where filtration occurs.

- **Option 3: Uriniferous Tubule**: This term refers to the nephron as a whole, which includes both the glomerulus and the renal tubules. It does not specifically refer to the formation of the glomerulus.

- **Option 4: Vasa Recta**: This option is incorrect. The vasa recta are specialized capillaries that supply blood to the renal medulla and are not involved in forming the glomerulus.

3. **Conclusion**: After evaluating all the options, we conclude that the correct answer is **Option 2: Afferent Arteriole**, as it is responsible for forming the glomerulus.

### Final Answer:
The glomerulus is formed by the **Afferent Arteriole**.
