Trace the ductal pathway from the epididymis to the urethra. (Module 26.5C)
iragen [17]

Answer:

epididymis

ductus deferens

ampulla of ductus deferens

seminal gland

ejaculatory duct

urethra

Explanation:

Epididymis is a tube that connects the back side of the testicles to the vas deferens (ductus deferens). The vas deferens is the connecting link between epididymis and urinary tract/urethra and is responsible for transporting sperm to the urethra. Seminal vesicles are small glands that lie above the prostate gland and make up more than 50% of the total semen. Seminal vesicles are connected to the vas deferens through ejaculatory duct. This duct empties sperm and semen into the urethra

Hence, the correct order is

epididymis

ductus deferens

ampulla of ductus deferens

seminal gland

ejaculatory duct

urethra
