THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The vas deferens (singular) is also called a ductus deferens or a sperm duct. This long muscular tube runs from the epididymis into the pelvic cavity behind your bladder and connects to your urethra through a structure called the ejaculatory duct.

Detailed explanation-2: -The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy. Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra above the seminal colliculus.

Detailed explanation-3: -What is an ejaculatory duct? Each of your two testicles has a vas deferens that joins with each of your seminal vesicle ducts to form your ejaculatory ducts (EDs). The EDs move through your prostate and pick up prostatic fluid to add to the semen. The fluid empties into your urethra.

Detailed explanation-4: -The ejaculatory ducts form where the vas deferens join with the ducts of the seminal vesicles in the prostate gland. They connect the vas deferens with the urethra. The ejaculatory ducts carry sperm from the vas deferens, as well as secretions from the seminal vesicles and the prostate gland that together form semen.
