What is the function of the vas deferens?

The vas deferens is a crucial component of the male reproductive system, serving the specific function of transporting sperm from the epididymis, where sperm is stored and matured, to the urethra. This function is vital because it enables the passage of sperm during ejaculation. The vas deferens has muscular walls that help propel the sperm forward through peristaltic movements. By facilitating this transport, the vas deferens plays an essential role in reproduction, allowing sperm to reach the female reproductive tract.

Other options do not pertain to the vas deferens. The filtering of blood is a function of the kidneys, hormone production is associated with glands such as the testes and adrenal glands, and urine storage is primarily the role of the bladder. Thus, the functions described in those options do not relate to the anatomical and physiological role of the vas deferens.
