What is the primary respiration organ of reptiles?

Explanation:
Gas exchange in reptiles happens primarily in the lungs. Reptiles are air-breathing and rely on lungs to take in oxygen from the air and remove carbon dioxide. While a little oxygen can diffuse through the skin in some species, that skin-based exchange is minor and not the main way they breathe. Gills, which are specialized for extracting oxygen from water, are used by fish and some amphibians, not by adult reptiles. The trachea is simply the airway that carries air to the lungs, not the site where most gas exchange occurs. So the lungs are the key organ for respiration in reptiles.
