The female frog's reproductive system includes two ovaries, which produce eggs. These eggs are released into the body cavity and are then captured by the oviducts. The eggs are fertilized externally when the male releases sperm, and they are then laid in water. The cloaca is a common opening for excretion and reproductive activities in female frogs, allowing them to lay their eggs into water for development. This is known as external fertilization, typical of amphibian reproduction.
