MICROANATOMY

Detailed explanation-1: -The ductus deferens, or vas deferens, is a fibromuscular tube that is continuation of the epididymis and is an excretory duct of the testis.

Detailed explanation-2: -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-3: -Mature sperm begin their journey by travelling from the epididymis to the vas deferens, which propels sperm forward with smooth muscle contractions. The sperm arrive first at the ampulla just above the prostate gland. Here, secretions from the seminal vesicle located next to the ampulla are added.
