Full Answer

While lungs are required for all reptiles, how the air gets in and out of the lungs varies by species. Some species move air in and out of the lungs by axial musculature, while others use buccal pumping to be able to run for long distances without needing to stop to breathe. Crocodilians are the reptiles that breathe in a manner most similar to humans.
