Final answer:
The path starting from the vas deferens and ending with the urethra includes the vas deferens, inguinal canal, pelvic cavity, seminal vesicles, ejaculatory duct, urethra, bladder, prostate, and bulbourethral/cowpers glands.
Step-by-step explanation:
The path starting from the vas deferens and ending with the urethra is as follows:
- Vas deferens: It begins at the epididymis and extends into the abdominal cavity through the inguinal canal.
- Inguinal canal: The vas deferens passes through this canal in the abdominal wall.
- Pelvic cavity: The vas deferens continues from the inguinal canal into the pelvic cavity.
- Seminal vesicles: The vas deferens then connects with the ducts of the seminal vesicles in the prostate gland.
- Ejaculatory duct: The ejaculatory ducts form where the vas deferens join with the ducts of the seminal vesicles in the prostate gland.
- Urethra: The ejaculatory ducts then connect with the urethra.
- Bladder: The urethra passes through the prostate gland inferior to the bladder.
- Prostate: The urethra passes through the prostate gland.
- Bulbourethral/cowpers: The urethra is joined by the bulbourethral glands, also known as Cowper's glands, which secrete mucus into the urethra.
