What: " Normally, the bladder is like a bag that has two functions. One is to store urine. The second is to contract and squeeze out the urine when you are ready to empty the bladder. The sphincter muscle is responsible for maintaining the closure of the urethra and surrounds the exit to the bladder at its connection with the urethra. The urethra is the tube that passes through the prostate and then through the penis where it ultimately exits near the tip at the meatus. "
