Question

Bidder's canal is present in
A. Female frog
B. Male frog
C. Female rabbit
D. Male rabbit

Answer 1

Hint: The reproductive system of frogs are specialized for external fertilization, as male frogs don't have specific path for releasing the the gamete so male frog uses their urethra for releasing gametes. and this bidders canal work as a bridge between vas deferens and the kidney so that the gamete from the Vas deferens could be released on kidney which can further be pass out for fertilization during reproduction.

Complete answer:
 In frogs, testicles and kidneys are available extremely near one another. The sperms are moved from the testicles into the bidder's channel through vasa efferentia. The Bidder's waterway stays associated with the ureter by cross-over dividers and structures the urogenital channel which opens into cloaca from where the two sperms and pee are dropped.

Bidder's waterway is present in male frogs. Vasa-efferentia opens into the bidder's channel and the bidder's waterway is associated with longitudinal gathering tubules by methods for various cross-over gathering conduits and helps in the death of the sperms and this trench also interfaces the genital and urinary pieces of the kidney.

Bidder's trench is present inside the kidney of the frog. It gets sperms from testicles through various vasa efferentia. It speaks with the ureter, which leaves the kidney close to its caring end and opens into the cloaca.

Hence the correct answer is option is (C).

Note: In frogs, pee delivered by nephrons will stream into the ureter from the longitudinal gathering conduit. Bidder's channel stays associated with this by a few crossover gathering tubules.
