What are two ways that respiration occurs in the adult frog?

Adult frogs primarily respire through two methods: cutaneous respiration and pulmonary respiration. Cutaneous respiration involves the exchange of gases through their skin, which must remain moist to facilitate this process. Additionally, frogs use pulmonary respiration by inhaling and exhaling air through their lungs, especially during periods of activity or when more oxygen is needed. This dual method allows frogs to efficiently meet their metabolic demands in various environments.
