Skin is an accessory organ of respiration in
Frogs
In frogs, respiration occurs in three ways.
1. Cutaneous respiration: Frogs respire through the skin. This happens during aestivation and hibernation.
2. Buccopharyngeal respiration: This occurs through the buccal cavity when the frog is out of water.
3. Pulmonary respiration: Lungs are used for respiration.
