Path sequence describing the order from production to exit for sperm

Path sequence describing the order from production to exit for sperm

• A. Epididymis -> Seminiferous Tubules -> Vas Deferens -> Ejaculatory Duct -> Urethra
• B. Seminiferous tubules -> Vas Deferens -> Epididymis -> Ejaculatory Duct -> Urethra
• C. Vas Deferens -> Ejaculatory Duct -> Urethra -> Epididymis -> Seminiferous Tubules
• D. Seminiferous tubules -> Epididymis -> Vas Deferens -> Ejaculatory Duct -> Urethra

Answer: (D)

Sperm begin their journey in the seminiferous tubules inside the testes, where they are produced. They then move to the epididymis, where they mature and are stored until ejaculation. During ejaculation, they travel through the vas deferens, enter the ejaculatory duct to mix with fluids from the seminal vesicles and prostate, and finally move into the urethra to exit the body. This order—production, maturation, transport, mixing with fluids, and exit—is why this sequence is correct. Placing the epididymis before production or skipping the maturation step would not reflect how sperm are formed and prepared for delivery, and placing the vas deferens before the epididymis disrupts the transport path.
