Amphibians like frogs use cutaneous respiration, where gas exchange occurs through their moist skin in addition to lungs. This follows from NCERT principle where relation explains outcome clearly for students.

Amphibians like frogs use cutaneous respiration, where gas exchange occurs through their moist skin in addition to lungs.

During hibernation, frogs rely on cutaneous respiration, where oxygen is absorbed through their moist skin.

Frogs use cutaneous respiration, where gases are exchanged through their moist skin while underwater.
Ref: NCERT Class 11 Biology Chapter 7: Structural Organisation in Animals Frog - Morphology and External Features
Respiration in adult frogs employs trimodal surfaces across seasons: cutaneous diffusion through highly vascularized thin moist skin effective both in water during hibernation under mud and on land, pulmonary respiration via paired sac-like septate lungs ventilated by positive-pressure buccal pumping expanding lungs, and buccopharyngeal respiration through highly vascular lining of oral cavity showing rhythmic throat oscillations enabling air sampling. Combined utilization allows tolerance to diving, overwintering anoxia and vocalization. Not restricted to single mode unlike mammals dependent solely on lungs for gas exchange.
