THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The urethra is the channel that carries the sperm (in fluid called semen) to the outside of the body through the penis. The urethra is also part of the urinary system because it is also the channel through which pee passes as it leaves the bladder and exits the body.

Detailed explanation-2: -Vas deferens: The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.

Detailed explanation-3: -The muscle at the opening of the bladder (bladder neck muscle) tightens to prevent ejaculate from entering the bladder as it passes from the prostate into the tube inside the penis (urethra). This is the same muscle that holds urine in your bladder until you urinate.

Detailed explanation-4: -Answer. ASSERTION is FALSE as it is the URETHRA who forms the common passage for both the sperms and urine.
