Question: 1 / 495

Which structure of the male reproductive system carries sperm cells from the testes to the lower part of the abdomen?

Urethra

Seminiferous tubules

Epididymis

Vas deferens

The vas deferens plays a vital role in the male reproductive system by transporting sperm cells. After sperm production occurs in the seminiferous tubules of the testes, the sperm then moves to the epididymis, where they mature and are stored. The vas deferens is the duct that carries fully matured sperm from the epididymis on each side to the ejaculatory duct, which ultimately leads to the urethra.

Understanding the functions of each structure helps clarify why the vas deferens is the correct answer in this context. The urethra, while involved in expelling sperm, does not transport sperm from the testes, and the seminiferous tubules are where sperm is produced, not where it is carried. The epididymis is involved in maturation and storage but does not perform the function of transporting sperm to the abdomen. Thus, the vas deferens is specifically suited for moving sperm from the testes to the lower abdomen region and beyond.
