Question

During aestivation and hibernation, frogs respire through ______

• A. lungs
• B. skin
• C. buccal cavity
• D. all of the above

Answer 1

The correct option is B skin

Frog respires through skin, lungs and buccal cavity. The respiration by lungs is called pulmonary respiration. The respiration by skin is called cutaneous respiration. The buccal cavity of frog is highly vascular and also helps in respiration and this is called bucco pharyngeal respiration. During aestivation and hibernation, gaseous exchange takes place through skin . During this period, the activities of frogs are relatively lower and they require less energy.
