Which of the following is the correct pathway of sperm cells from their formation to ejaculation?

• A. Vas deferens, seminiferous tubules, epididymis, ejaculatory duct, urethra
• B. Seminiferous tubules, epididymis, vas deferens, ejaculatory duct, urethra
• C. Seminiferous tubules, vas deferens, epididymis, urethra, ejaculatory duct
• D. Epididymis, seminiferous tubules, vas deferens, urethra, ejaculatory duct

Answer: (B)

Verified step by step guidance

1. Identify the starting point of sperm production, which occurs in the seminiferous tubules located within the testes.
2. Understand that after formation, sperm cells move to the epididymis, where they mature and are stored.
3. Recognize that during ejaculation, sperm travel from the epididymis into the vas deferens, a muscular tube that propels sperm forward.
4. Note that the vas deferens leads to the ejaculatory duct, where sperm mix with seminal fluid to form semen.
5. Finally, semen is expelled through the urethra, which is the last part of the pathway during ejaculation.
