What is the urinary system of frogs?

ovary-oviduct-uterine enlargement-cloaca
In a female frogâ??s body, the ovaries make the eggs. The eggs then move though the oviducts and then they exit the frogâ??s body through the cloaca.
Frogs lay their eggs in water. These hatch into tadpoles, which then turn into frogs who live on land. While in the female, eggs are made in the ovaries, then they move into the uterus, where they are fertilized.
