PATHOLOGY

Detailed explanation-1: -Sperm are stored in the proximal portion of the ductus deferens, near the epididymis, and peristaltic movements propel the sperm through the tube. The proximal portion of the ductus deferens is a component of the spermatic cord, which contains vascular and neural structures that supply the testes.

Detailed explanation-2: -Smooth muscle tissue in the walls of the ductus deferens contracts in waves of peristalsis to slowly move sperm along its length.

Detailed explanation-3: -Answer and Explanation: The duct that carries sperm from the epididymis to the ejaculatory duct is the vas deferens. There is one duct for each epididymis. These ducts utilize smooth muscle to move sperm via peristalsis.
