The shared terminal duct of the reproductive and urinary system in the human male is

Options

A. vasa efferentia
B. urethra
C. ureter
D. vas deferens

Answer

To solve the question regarding the shared terminal duct of the reproductive and urinary system in the human male, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Systems Involved**:
- The question mentions two systems: the reproductive system and the urinary system. We need to find the duct that serves as a common pathway for both systems in males.

2. **Understand the Components of the Reproductive System**:
- In the male reproductive system, key components include the testes (where sperm is produced), the epididymis (where sperm matures), and the vas deferens (which transports mature sperm).

3. **Understand the Components of the Urinary System**:
- The urinary system includes the kidneys (which filter blood to produce urine), ureters (which carry urine from the kidneys to the bladder), the bladder (which stores urine), and the urethra (which expels urine from the body).

4. **Identify the Shared Duct**:
- The urethra is the duct that serves both systems. It carries urine from the bladder and also serves as the passage for semen during ejaculation.

5. **Evaluate the Options**:
- The options provided are:
- A) Vasa deferens
- B) Urethra
- C) Ureter
- D) Vas deferens
- Among these, the urethra is the only structure that connects both the urinary and reproductive systems.

6. **Conclusion**:
- Therefore, the shared terminal duct of the reproductive and urinary system in the human male is the **urethra**.

### Final Answer:
**Urethra**
