Question

Explain the female reproductive system of frog.

Accepted Answer

The frog is a unisexual animal. The female reproductive organs include a pair of ovaries. The ovaries are situated near the kidneys and there is no functional connection with the kidneys. A pair of oviducts arising from the ovaries opens into the cloaca separately. A mature female can lay 2500 to 3000 over at a time. The female reproductive system consists of paired ovaries, attached to the kidneys, and the dorsal body wall by folds of the peritoneum called mesovarium. There is a pair of coiled oviducts lying on the sides of the kidney. Each oviduct opens into the body cavity at the anterior end by a funnel-like opening called Ostia. Unlike the male frog, the female frog has separate genital ducts distinct from ureters. Posteriorly the oviducts dilated to form ovisacs before they open into the cloaca. Ovisacs store the eggs temporarily before they are sent.
