The correct order of the reproductive tract of a male human being is

Options

A. Rete testis, epididymis, vasa efferentia, urethra
B. Rete testis, vasa efferentia, epididymis, urethra
C. Vasa efferentia, epididymis, urethra, rete testis
D. Urethra, rete testis, epididymis, vasa efferentia

Explanation

To determine the correct order of the reproductive tract of a male human being, we can follow these steps:

### Step 1: Identify the Components of the Male Reproductive Tract
The male reproductive tract consists of several key structures, including:
- Testes
- Rete testis
- Epididymis
- Vas deferens (also known as ductus deferens)
- Urethra

### Step 2: Understand the Sequence of Structures
The sequence in which sperm travels through the male reproductive tract is as follows:
1. **Testes**: Sperm is produced in the testes.
2. **Rete Testis**: Sperm moves from the seminiferous tubules of the testes into the rete testis.
3. **Epididymis**: From the rete testis, sperm enters the epididymis, where it matures and is stored.
4. **Vas Deferens**: The mature sperm then travels through the vas deferens.
5. **Urethra**: Finally, sperm is expelled through the urethra.

### Step 3: Write the Correct Order
Based on the above sequence, the correct order of the male reproductive tract is:
1. Rete Testis
2. Epididymis
3. Vas Deferens
4. Urethra

### Conclusion
Thus, the correct order of the reproductive tract of a male human being is:
**Rete Testis → Epididymis → Vas Deferens → Urethra**
