Question

During hibernation, Frog respires through

• A. Buccopharyngeal cavity
• B. Skin/integument
• C. Skin and lungs
• D. Skin, lungs and buccopharyngeal cavity

Answer 1

The correct option is B Skin/integument

The skin of the frog provides an extensive surface for the exchange of gases. It is thin, richly supplied with blood and kept moist by the mucus and water. The cutaneous respiration is always carried out. During hibernation (winter sleep) and aestivation (summer sleep), it is the only method of respiration in a frog. This is also known as cutaneous respiration.

So the correct answer is 'Skin/integument'.
