Vasa efferentia connect the

Options

A. testes with epididymis
B. kidneys with cloaca
C. testes with urinogenital duct
D. None of the above

Answer

To answer the question "Vasa efferentia connect the," we will analyze the options provided and understand the role of vasa efferentia in the male reproductive system.

### Step-by-Step Solution:

1. **Understanding the Structure**: The vasa efferentia are a series of small ducts that transport sperm from the seminiferous tubules of the testes to the epididymis.

2. **Location of Vasa Efferentia**: Each testis contains about 250 testicular lobules, and within these lobules are the seminiferous tubules where sperm is produced. The vasa efferentia connect these seminiferous tubules to the epididymis.

3. **Connection to Epididymis**: The vasa efferentia serve as a pathway for sperm to move from the testis to the epididymis, where sperm mature and are stored.

4. **Evaluating the Options**:
- **Testis with Epididymis**: This is correct as vasa efferentia connect the testis to the epididymis.
- **Kidneys with Cloaca**: This is incorrect; vasa efferentia do not connect these structures.
- **Testis with Urinary Genital Duct**: This is also incorrect; the vasa efferentia do not connect these directly.
- **None of the Above**: This option is incorrect since we have identified a correct connection.

5. **Conclusion**: Based on the understanding of the male reproductive system and the function of vasa efferentia, the correct answer is that vasa efferentia connect the testis with the epididymis.

### Final Answer:
**Vasa efferentia connect the testis with the epididymis.**
