The blood vessel supplying blood into Bowman's capsule is

Options

A. Afferent arteriole
B. Efferent arteriole
C. Renal vein
D. Renal portal vein

Answer

### Step-by-Step Solution:

1. **Identify the Structure**: Understand that Bowman's capsule is a part of the nephron in the kidney and is responsible for the initial filtration of blood.

2. **Understand Blood Flow**: Recognize that blood enters the nephron through specific blood vessels. The blood supply to Bowman's capsule is crucial for its function.

3. **Differentiate Between Blood Vessels**:
- **Afferent Arteriole**: This is the blood vessel that brings blood into the glomerulus, which is located within Bowman's capsule.
- **Efferent Arteriole**: This vessel carries blood away from the glomerulus.
- **Renal Vein**: This vein drains blood from the kidneys and does not supply blood to Bowman's capsule.
- **Renal Portal Vein**: This is not present in humans and is involved in different circulatory systems.

4. **Conclusion**: The blood vessel that supplies blood into Bowman's capsule is the **afferent arteriole**.

### Final Answer:
The blood vessel supplying blood into Bowman's capsule is the **afferent arteriole**.
