Which organ system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis?

• A. Nervous System
• B. Male Reproductive System
• C. Digestive System
• D. Circulatory System

Answer: (B)

The organs listed all belong to the male reproductive system, which is responsible for producing, storing, and delivering sperm. The testes make sperm and hormones like testosterone; the epididymis stores and matures sperm; the vas deferens transports sperm from the epididymis toward the urethra; seminal vesicles and the prostate gland add fluids to semen; and the penis delivers semen during ejaculation. Other choices refer to the nervous, digestive, or circulatory systems, which do not include these reproductive structures. So the male reproductive system is the correct fit.
