Question

which of the following describes the epididymis?
a tube that transports sperm to the urethra
a vesicle that produces fluid and gives sperm nourishment and motility
a gland that contributes fluid to semen
a tube that stores and develops sperm cells from the testes

Explanation:

The epididymis is a coiled - tube structure. Sperm produced in the testes move to the epididymis where they are stored and mature to gain motility. It is not the tube that transports sperm to the urethra (vas deferens does that), not a vesicle producing fluid for sperm nourishment (seminal vesicles etc. do that), and not a gland contributing fluid to semen.

Answer:

a tube that stores and develops sperm cells from the testes
