Question

Select the correct route for the passage of sperms in male frogs :

• A. Testes $\to$ Bidder's canal $\to$ Kidney $\to$ Vasa efferentia $\to$ Urogenital duct $\to$ Cloaca
• B. Testes $\to$ Vasa efferentia $\to$ Kidney $\to$Seminal vesicle $\to$Urogenital duct $\to$Cloaca
• C. Testes $\to$ Vasa efferentia $\to$ Bidder's canal $\to$Ureter $\to$Cloaca
• D. Testes $\to$ Vasa efferentia $\to$ Kidney $\to$ Bidder's canal $\to$ Urogenital duct $\to$ Cloaca

Answer 1

The correct option is D Testes $\to$ Vasa efferentia $\to$ Kidney $\to$ Bidder's canal $\to$ Urogenital duct $\to$ Cloaca

In frogs, the vasa efferentia arises from the testes. They enter the kidneys on their respective side and open into the Bidder’s canal. The vasa efferentia meets the urogenital duct that comes out of the kidneys and they open together into the cloaca. The cloaca is a small, median chamber that is used to pass faecal matter, urine and sperms to the exterior. So, the correct route for the passage of sperms in male frogs will be:
Testes $\to$ Vasa efferentia $\to$ Kidney $\to$Bidder's canal$\to$Urogenital duct $\to$Cloaca
