Final Answer:
A system of ducts carries sperm cells out of the testes through the epididymis, two seminal ducts known as vas deferens, two ejaculatory ducts, and the urethra.
Step-by-step explanation:
Epididymis:
Sperm cells produced in the testes move into the epididymis, a coiled tube where they mature and gain the ability to swim.
Vas Deferens:
From the epididymis, sperm travel through two vas deferens (seminal ducts), which are muscular tubes that propel sperm towards the urethra during ejaculation.
Ejaculatory Ducts:
The vas deferens joins with the seminal vesicles, forming two ejaculatory ducts. These ducts pass through the prostate gland and enter the urethra.
Urethra:
Finally, the urethra serves as the common passage for both sperm and urine, extending from the ejaculatory ducts to the external opening.
