Which part of the sperm duct helps in transportation of sperms to epididymis?

Options

A. Rete testis
B. Vasa effe rentia
C. Ejaculatory duct
D. Vasa deferentia

Answer

To answer the question regarding which part of the sperm duct helps in the transportation of sperm to the epididymis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Parts of the Sperm Duct**:
- The sperm duct consists of several parts, including the seminiferous tubules, rete testis, vasa efferentia, epididymis, and ejaculatory duct.

2. **Understand the Function of Each Part**:
- **Seminiferous Tubules**: This is where sperm is produced.
- **Rete Testis**: This structure collects sperm from the seminiferous tubules.
- **Vasa Efferentia**: These are small ducts that transport sperm from the rete testis to the epididymis.
- **Epididymis**: This is where sperm matures and is temporarily stored.
- **Ejaculatory Duct**: This duct carries sperm from the epididymis to the urethra for ejaculation.

3. **Focus on the Transportation to Epididymis**:
- The question specifically asks about the part that helps in transporting sperm to the epididymis.
- The **vasa efferentia** are the ducts that connect the rete testis to the epididymis and are responsible for transporting sperm to the epididymis.

4. **Conclusion**:
- Therefore, the part of the sperm duct that helps in the transportation of sperm to the epididymis is the **vasa efferentia**.

### Final Answer:
The part of the sperm duct that helps in the transportation of sperm to the epididymis is the **vasa efferentia**.
