Small airways are mainly located at the 7 generation, where cartilaginous structures are present despite reduced distribution in more distal airways, and the thickness decreased in greater age. Reduction in luminal area of medium-to-small airways might be the morphological changes associated with ageing (i.e. > 55 years of age).
