Lung Books

 

blind processes of the lungs of certain reptiles.

The lung books of chameleons are especially numerous and varied in shape, inflating greatly with air when the animal adopts a threatening pose. The walls of lung books are thin and usually smooth (less often, alveolar). Lung books are one of the varieties of air sacs.
