Which of these structures transports sperm from the testis to the penis?
Correct answer: A. Sperm duct
- A. Sperm duct
- B. Scrotum
- C. Urethra
- D. Gamete
Explanation
The structure that transports sperm from the testes to the penis is the vas deferens. The vas deferens is a duct that is part of the male reproductive system. It extends from the epididymis, where sperm mature and are stored, through the inguinal canal, and it eventually joins with the duct from the seminal vesicle to form the ejaculatory duct. The ejaculatory duct then passes through the prostate gland and empties into the urethra, which extends through the penis. During ejaculation, sperm travel through the vas deferens to reach the urethra and are then expelled from the body through the penis.
