7900 species alive today

Trutles, tortoises, snakes, alligators and lizards. How does the system work? Reptiles have a complete respiratory system
They have lungs, trachea, glottis and nostrils. The air is brought through the trachea which is composed of several cartilaginous rings.
The trachea never divides into bronchial ramifications.
The air goes into a cavity or two that opens to the lung
