Ques. 1AIPMT 2011 (Mains)
Ureters act as urinogenital ducts in
- human males
- human females
- both male and female frogs
- male frogs
Answer
(4) male frogs
Solution
As per NCERT, in male frogs the ureters act as urinogenital ducts: the vasa efferentia from the testes open into the Bidder's canal, which joins the ureter, so the ureter carries both urine and sperms into the cloaca.
In female frogs, by contrast, the ureters carry only urine, as the oviducts open separately into the cloaca.
In human males it is the urethra (not the ureter) that is the common urinogenital passage.
