Question

what 45-centimeter structure of the male reproductive system connects the epididymis to the ejaculatory duct?
a. bulbourethral gland
b. seminal vesicle
c. prostate gland
d. vas deferens

Explanation:

To solve this, we analyze each option:

• Option A (bulbourethral gland): Produces pre - ejaculatory fluid, not a connecting duct.
• Option B (seminal vesicle): Produces seminal fluid, connects to ejaculatory duct but not directly from epididymis.
• Option C (prostate gland): Secretes prostate fluid, not a connecting duct.
• Option D (vas deferens): Transports sperm from epididymis to ejaculatory duct.

Answer:

D. vas deferens
