Answer

To identify the complete and correct sequence in the passage of spermatozoa, we need to understand the anatomical pathway that sperm takes from their formation to ejaculation. Here’s the step-by-step breakdown:

### Step-by-Step Solution:

1. **Formation in Seminiferous Tubules**: Spermatozoa are produced in the seminiferous tubules located within the testes. This is the starting point of sperm development.

2. **Rete Testis**: After formation, spermatozoa move into the rete testis, a network of tubules that collects sperm from the seminiferous tubules.

3. **Vasa Efferentia**: From the rete testis, sperm travel through the vasa efferentia, which are small ducts that connect the rete testis to the epididymis.

4. **Epididymis**: The spermatozoa then enter the epididymis, where they mature and are stored. This is a crucial step for sperm to gain motility and the ability to fertilize an egg.

5. **Vas Deferens**: After maturation, sperm move into the vas deferens, a muscular tube that transports sperm from the epididymis to the ejaculatory duct.

6. **Ejaculatory Duct**: The sperm then enter the ejaculatory duct, which is formed by the union of the vas deferens and the duct from the seminal vesicle.

7. **Urethra**: From the ejaculatory duct, sperm travel into the urethra, which serves as the passageway for sperm to exit the body.

8. **Vagina of Female**: Finally, during ejaculation, sperm are expelled into the vagina of the female, where they can potentially fertilize an ovum.

### Complete Sequence:
The complete and correct sequence of the passage of spermatozoa is:
1. Seminiferous Tubules
2. Rete Testis
3. Vasa Efferentia
4. Epididymis
5. Vas Deferens
6. Ejaculatory Duct
7. Urethra
8. Vagina of Female
