Question

• A. Cutaneous
• B. Buccal
• C. Pulmonary
• D. All the above

Answer 1

Answer: (D)

All the above

In adult frog, due to its amphibious mode of life, respiration occurs through the skin (cutaneous respiration), lining of the buccopharyngeal cavity (buccal respiration) and the lungs (pulmonary respiration). Ordinary respiratory requirements are met by the skin and buccopharyngeal cavity, lungs are used only when the need for oxygen is great.

So, the correct answer is 'All the above'.
