What is the passage of sperm from formation to exterior?

• A. Testes, vas deferens, epididymis, ejaculatory duct, urethra
• B. Testes, epididymis, vas deferens, ejaculatory duct, urethra
• C. Testes, epididymis, vas deferens, urethra, ejaculatory duct
• D. Testes, epididymis, urethra, vas deferens

Answer: (C)

Sperm travel in a specific, unidirectional path from production to exit. They are formed in the testes and then move to the epididymis, where they mature and are stored. From the epididymis they pass into the vas deferens, which transports them during ejaculation. The vas deferens and ducts from the seminal vesicles join to form the ejaculatory duct, which then empties into the urethra. Finally, the semen travels through the urethra to exit the body. Because the ejaculatory duct feeds into the urethra, the correct sequence places the ejaculatory duct before the urethra.
