The vas deferens is a muscular tube that transports sperm from the epididymis, where sperm mature and are stored, to the ejaculatory duct in preparation for ejaculation. It plays a crucial role in the male reproductive system by allowing sperm to move from the testes, located in the scrotum, to the lower part of the abdomen and then into the urethra during ejaculation.

The urethra is responsible for carrying urine from the bladder and sperm from the reproductive tract but does not transport sperm directly from the testes. The seminiferous tubules are located within the testes and are responsible for the production of sperm, not their transportation. The epididymis serves as a storage site for sperm and is where they mature, but it does not function as a conduit to transport sperm to the abdomen. Thus, the vas deferens is specifically designed for the movement of sperm cells, making it the correct answer.
