From there, urine travels out of the kidneys through the ureters to be stored in the bladder (a muscular sac in the lower abdomen). The bladder expands as it fills and can hold about 2 cups (half a liter) of urine at any given time (the average adult produces about 6 cups, or 1Â½ liters, of pee per day).
Your kidneys, which are the main part of the urinary system, are made up of millions of nephrons that act as individual filtering units and are complex structures themselves. The ureters, urethra, and urinary bladder complete this intricate system. The urinary system helps maintain homeostasis by regulating water balance and by removing harmful substances from the blood. The blood is filtered by two kidneys, which produce urine, a fluid containing toxic substances and waste products.
