Current Question (ID: 14407)

Question:

Frogs respire through

Options:

1. Skin
2. Lungs
3. Buccal cavity
4. All of these

Solution:

All are the respiratory organs of frog in different habitats. Frogs respire through all of these: skin, lungs, and buccal cavity. Frogs are amphibians, and their respiratory system is adapted to their semi-aquatic lifestyle. When submerged in water, they primarily respire through their skin, which is moist and permeable to gases. This is known as cutaneous respiration. When on land, frogs can also use their lungs to respire, much like humans. However, their lungs are relatively simple in structure, with only a few large chambers, and are not as efficient as mammalian lungs. Finally, frogs can also use their buccal cavity (mouth) to aid in respiration. They have a special pumping mechanism where they alternately close their nostrils and force air into their lungs using their buccal cavity. This is known as buccal pumping.
