What is the bearded dragons respiratory system?

Bearded dragons have a unique respiratory system that includes lungs, which are relatively large and efficient for gas exchange. They breathe through their nostrils and can also utilize their mouth for respiration. Unlike some reptiles, bearded dragons do not have a diaphragm, so they rely on the expansion and contraction of their body wall to facilitate breathing. This system allows them to efficiently take in oxygen and expel carbon dioxide, supporting their active metabolism.
