Question

Which structure is not related with respiration in frog?

• A. Lungs
• B. Skin
• C. Buccal cavity
• D. Diaphragm

Answer 1

The correct option is D Diaphragm

Being an amphibian, the frog shows different modes of respiration based on environmental and physiological conditions. Frogs mainly respire either via their skin, mouth, lungs, or gills. Adult frogs lose their gills and respire via lungs, skin and their mouth. The lack of a diaphragm makes them use their mouth, nostrils, and mouth to expel gases.

So, the correct answer is 'Diaphragm'.
