The urine collected from the kidney is sent to the urinary bladder through the ureter. It is stored there until it is excreted. The capacity of the urinary bladder is around 600 ml. When the urinary bladder is full, a signal is sent from the brain. This makes the walls of the urinary bladder to contract and relax, sending the urine out through the urethra.
