A mature female can lay 2500 to 3000 ova at a time. Digestive System of Frog: Frog is a carnivorous animal. External fertilization is seen in frogs and occurs in water. The ureter does not dilate as vesicula seminalis and no ducts from ovaries open into the kidneys. The female reproductive system is designed to carry out several functions. Note. Testes - Male sex organs that produce sex cells (sperm). The male bird's sexual organs consist of paired testis. Thereafter it becomes It is divided into three parts.

Ovaries are little structures consisting three layers, outer theca external, middle germinal epithelium and inner theca internal which consist blood cells, muscle cells, nerves cells and germinal epithelium.
