Explain the male reproductive system of frog.

Explanation

Reproductive system: The male frog has a pair of testes which are attached to the kidney and the dorsal body wall by folds of peritonium called mosocrchim. Aasa efferentia arise from each testis. They entey the kidneys on both side and open into the bladder canal. Finally. it communicates with the urinogenital duct that comes out of kidneys and opens into the cloaca.
Female reproductive system consists of paired overies. attached to the kidneys, and dorsal body wall by folds of peritoneum called mesovarium. There is pair of coiled oviducts lying on the sies of the kidney. Each oviduct opens into the body-cavity at the anterior end by a funnel like opening celled 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 cloaca. Ovisacs store the cggs temporarily before they are sent out through the cloaca. Fertilization is external.
Within few days of fertilization, the eggs hatch into ladpoles. A newly hatched tadpole lives off the yolk stroed in its body. It gradually grows larger and develos three pairs of gills. The tadpole grows and metamorphosis into an air- breathing camivorous adult frog. Legs grow from the body, and the tail and gills disappear. The mouth broadens, developing teeth and jaws, and the lungs become functional.
