Which of the Following is a Correct Sequence Regarding the Flow

Question

Which of the following is a correct sequence regarding the flow of semen or semen-to-be?
A) Vas deferens, seminiferous tubules, urethra
B) Urethra, ejaculatory duct, vas deferens
C) Seminiferous tubules, vas deferens, epididymis
D) Vas deferens, ejaculatory duct, urethra

Accepted Answer

The sperm cells are produced in the seminiferous tubules, and then travel to the epididymis to mature and be stored. When it's time for ejaculation, the sperm cells leave the epididymis and move to the vas deferens. Next, the sperm cells pass through the ejaculatory duct and into the urethra, where they mix with fluids from the seminal vesicles, prostate gland, and bulbourethral glands to form semen, which is then ejaculated out of the penis. Therefore, the correct sequence is vas deferens, ejaculatory duct, urethra.
