The ______ secrete(s) fluid that helps to facilitate the movement of sperm
and encircles the urethra in males.
A. prostate gland
B. testes
C. seminal vesicles
D. epididymis
The correct answer is A. prostate gland.
The correct answer is A. prostate gland.
The answer to the question is option C: seminal vesicles.
To arrive at the correct answer, we can break down the question and analyze its components.
First, let's understand the function described in the question: secreting fluid that helps facilitate the movement of sperm. This suggests that we are looking for a gland or structure involved in the reproductive process that produces a fluid to support the motility of sperm.
Next, the question mentions that the structure encircles the urethra in males. This helps narrow down the possibilities since not all structures related to the reproductive system are positioned in this way.
Now, let's evaluate the answer choices:
A. Prostate gland: The prostate gland is a walnut-sized gland found in males that produces a milky fluid that nourishes and protects sperm. While the prostate gland is involved in the production of fluid, it does not encircle the urethra. Therefore, A is not the correct answer.
B. Testes: The testes are responsible for producing sperm and testosterone but do not secrete fluid to facilitate the movement of sperm. Additionally, testes do not encircle the urethra. Therefore, B is not the correct answer.
C. Seminal vesicles: The seminal vesicles are a pair of glands located behind the bladder and above the prostate gland. They produce a significant portion of the fluid that makes up semen. This fluid provides nourishment and energy to the sperm, allowing them to move more easily. Moreover, the seminal vesicles partially encircle the urethra. Therefore, C is the correct answer.
D. Epididymis: The epididymis is a coiled tube located on the back of each testicle that stores and transports sperm. It does not secrete fluid to facilitate sperm movement and does not encircle the urethra. Therefore, D is not the correct answer.
In conclusion, the correct answer is C. Seminal vesicles secrete fluid that helps facilitate the movement of sperm and encircles the urethra in males.
