Peritubular capillaries develop from

Options

A. Renal vein
B. Afferent arteriole
C. Efferent arteriole
D. Arcuate artery

Answer

To solve the question "Peritubular capillaries develop from," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: Peritubular capillaries are small blood vessels that surround the nephron in the kidney. They play a crucial role in the processes of reabsorption and secretion.

2. **Identify the Blood Flow**: Blood enters the glomerulus (a network of capillaries) through the afferent arteriole. This is where filtration occurs.

3. **Determine the Outflow**: After filtration, the blood exits the glomerulus through the efferent arteriole.

4. **Formation of Peritubular Capillaries**: The efferent arteriole branches into a network of capillaries that surround the nephron, which are known as peritubular capillaries.

5. **Conclusion**: Since peritubular capillaries develop from the efferent arteriole, the correct answer to the question is "efferent arteriole."

### Final Answer:
Peritubular capillaries develop from the efferent arteriole.
