Block4/Fig 14. Lung (NO-6-b)

block9_30.jpg - Fig 14. Lung (NO-6-b)The wall of the respiratory bronchiole consists of alternating thick and thin portions. The thin portion consists of recesses that have a wall similar to that of the alveoli (A) and thus capable of gas exchange. The thick portion has a wall formed by small cuboidal cells (CC) that appear to rest on a small bundle of smooth muscle (M, eosinophilic material) and is surrounded by a thin investment of connective tissue (CT). The thin regions have a wall similar to the alveolar wall (AW).
