What is the primary role of the vas deferens in the male reproductive system?
A
To secrete seminal fluid
B
To transport sperm from the epididymis to the ejaculatory duct
C
To store immature sperm
D
To produce testosterone
Verified step by step guidance1
Understand the anatomy of the male reproductive system: The vas deferens is a muscular tube that connects the epididymis to the ejaculatory duct. It plays a critical role in the transport of sperm during ejaculation.
Eliminate incorrect options: The vas deferens does not secrete seminal fluid. Seminal fluid is primarily produced by the seminal vesicles, prostate gland, and bulbourethral glands.
Eliminate another incorrect option: The vas deferens does not store immature sperm. Immature sperm are stored and mature in the epididymis.
Eliminate the final incorrect option: The vas deferens does not produce testosterone. Testosterone is produced by the Leydig cells in the testes.
Conclude the correct role: The primary role of the vas deferens is to transport sperm from the epididymis to the ejaculatory duct, where it mixes with seminal fluid to form semen before ejaculation.
