- Skin (Cutaneous Respiration) – Frogs can absorb oxygen directly through their moist skin, especially when underwater.
- Buccal Cavity (Buccopharyngeal Respiration) – They can also exchange gases through the lining of their mouth.
This adaptation helps them survive in both aquatic and terrestrial environments.
Why not the others?
- (A) Pleura – It is a membrane around human lungs, not an animal.
