Urinogenital System of frog

The excretory and reproductive systems are functionally unrelated but products of these two systems have common passage. In frog the sexes are separate hence it can be studied under two headings Male and female reproductive system.

Male reproductive system 

It consists of a pair of testes, vasa efferentia, bidder’s canal, transverse collecting tubules, urinogenital ducts, and cloaca.

Testes : Testes are elongated or oval, light yellow, is found attached to the anterior ventral side of each kidney to which they are suspended by a double fold of peritoneum called Mesorchium. Each testes consists coiled structures called seminiferous tubules. The epithelial lining of seminiferous tubules consists of germinal cells, which produce spermatozoa. Many seminiferous tubules unite to form vasa efferentia, which is narrow tube like structure.  The vasa efferentia runs through kidney and open into the Bidder’s canal, which is then connected to the ureter. The sperms pass through vasa efferentia, bidder’s canal, ureter and cloaca.  The urine and sperms pass through ureter so that it is also called as urinogenital duct. Each urinogenital duct ............
