What is the name of the tube that carries the sperm from the testes to the urethra?
Correct answer: D. Sperm duct
- A. Penis
- B. Seminal vesicles
- C. Prostate gland
- D. Sperm duct
Explanation
The tube that carries sperm from the testes to the urethra is called the vas deferens. The sperm duct, also known as the vas deferens, is a muscular tube that carries sperm from the epididymis (where sperm are stored after they are produced in the testes) to the urethra. The vas deferens is a long, muscular tube that functions as part of the male reproductive system. During ejaculation, sperm move from the testes through the vas deferens, where they mix with fluids from the seminal vesicles, prostate gland, and bulbourethral gland to form semen. The semen then travels through the urethra and is expelled from the body through the penis.
