Question

Bidder's canal is present in_________

• A. testis of frog
• B. kidney of frog
• C. cloaca of frog
• D. None of these

Answer 1

The correct option is B kidney of frog

In male frog, the urinary system and reproductive system are together. Each testis of frog is located anteroventrally towards the inner margin of the kidney. The vasa efferentia arise from each testis and enter the kidney to open in the Bidder's Canal. They are thin and slender. There are about 10 to 12 vasa efferentia in number. The Bidder's canal runs longitudinally along the inner margin of the kidney and communicates with the urinogenital duct by several transversely arranged collecting tubules.
