Correct Answer: Option B

Explanation

The bladder has three orifices for the incoming and outgoing of urine. The ureters from both kidneys enter the bladder and the urethra exits the bladder. The urethral sphincter controls the opening and closing of the urethra. The bladder is a muscular sac located in the pelvis which stores and releases urine. When the bladder is full, the brain sends a signal to the muscles of the bladder to contract and the urine is expelled through the urethra.
