In their bladder
The major organ of the urinary system is two bean shaped kidneys.
The bladder is part of the urinary system. The other system that has a bladder is the digestive system. It has the gall bladder.
Frogs have kidneys, an ureter and an urinary bladder, just like mammals, but also exchange substances through their skin eg: water.
Since amphibians evolved from fish and fish have one air bladder (or swim bladder), frogs have 1 lung. The air bladder evolved into a lung. Remember, frogs are also able to breathe through their skin.
Gall Bladder
The major parts of the urinary system are the Kidneys and bladder. The most important is the kidneys. The kidneys clean waste from the blood of a living organism and uses little water to help remove these wastes, sending the waste to the bladder and waiting for the release through the urethra. Another thing is that without the circulatory system the blood would not be able to be sent to the kidneys. For health reasons, try to not consume to much salts and minerals or the it is possible to get kidney failure. Hope this helps.
