What structure connects the epididymis to the body?

The structure that connects the epididymis to the body is the vas deferens, also known as the ductus deferens. It is a muscular tube that transports sperm from the epididymis to the ejaculatory duct, where it can be mixed with seminal fluid before ejaculation. The vas deferens runs from the epididymis through the spermatic cord and into the pelvic cavity.
