What is the purpose of the vas deferens?

The vas deferens is a muscular tube that carries sperm from the epididymis toward the urethra during ejaculation. Choice D, “to transport the sperm from the epididymis to the urethra,” describes this role. Sperm mature and are stored mainly in the epididymis, while seminal fluids are produced by glands such as the seminal vesicles and prostate.
