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: -Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.

Detailed explanation-3: -The epididymis functions to move sperm out of the testicles. Then, the epididymis connects to the vas deferens, which is different tube that connects the epididymis to the urethra.

Detailed explanation-4: -The epididymis sits directly on top of each testis. Sperm from the testis mature as they move through the coiled duct of the epididymis. During sexual intercourse and ejaculation, they are expelled into the vas deferens.
