Identify the correct sequential pathway for the transport of sperms from the testes to the outside in a male frog.

Step-by-step solution

In male frogs, sperms are produced in the testes. From the testes, 10 to 12 vasa efferentia arise and enter the kidneys on their respective sides. Inside the kidneys, they open into the Bidder's canal. The Bidder's canal finally communicates with the urinogenital duct that emerges from the kidneys and opens into the cloaca. The cloaca is a small, median chamber that is used to pass faecal matter, urine, and sperms to the exterior. Thus, the correct sequential pathway is: Testes Vasa efferentia Kidney Bidder's canal
