Final answer:
The vas deferens, also called the ductus deferens, is a tube that carries sperm from the epididymis to the ejaculatory ducts during ejaculation.
Step-by-step explanation:
The other name for vas deferens is ductus deferens. The vas deferens, also known as the sperm duct, is a vital component of the male reproductive system, tasked with transporting sperm from the epididymis to the ejaculatory ducts during ejaculation. This duct is bundled inside the scrotum with connective tissue, blood vessels, and nerves into the spermatic cord. A vasectomy, which is a form of birth control, involves cutting and sealing the vas deferens. The vas deferens is lined with smooth muscle to help propel sperm forward and is composed of ciliated epithelium.
