GENERAL HISTOLOGY

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 male body has a system that keeps it from being able to ejaculate and urinate at the same time. During sexual arousal, muscles at the base of the bladder contract in order to close off the passageway from the bladder into the urethra, the tube through which urine and semen leave the body.

Detailed explanation-3: -Urethra-this is a tube that extends from the bladder to the external opening at the end of the penis. The urethra carries both urine and sperm.

Detailed explanation-4: -The ejaculatory duct delivers sperm into the urethra, adding secretions and additives from the prostate necessary for sperm function, while providing an interface between the reproductive and urinary systems in men (see image below).
