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

Options

A. Testes `to` Bidder's canal `to` Kidney `to` Vase efferentia `to` Urinogen tal duct `to` Cloaca
B. Testes `to` Vasa efferentia `to` Kidney `to` Seminal vesicle `to` Urinogential duct `to` Cloaca
C. Test `to` Vasa efferentia `to` Bidder's canal `to` Ureter `to` Cloaca
D. Testes `to` Vasa efferentia rarr Kidney`to` Bidders canal `to` Urinogenital duct `to` Cloaca

Answer

D

Explanation

In male frogs, germinal epithelium of seminiferous tubules produce sperms, which are transferred to kidney via vasa efferentia, from the kidney, these enter into Bidder's canal from where, the sperms are caried to the transverse collecting tubules, longitudinal collecting tubule and then to unnogenital duct. The later carries the sperms to seminal vesical. where, they are stored temporarily. From here, sperms are carried to cloaca and then these shed into water.
Thus, the correct route of sperms passage is
