Emphysema is classified into three types based on histological morphology: centrilobular emphysema, which is caused by the destruction and enlargement of the respiratory bronchioles in the center of the lobule; panlobular emphysema, which is caused by the destruction and enlargement of the alveolar passages and alveolar sacs; and focal emphysema, which occurs in an isolated area around a scar or under the pleura. *Some of the terminology that mentions "focal emphysema" is listed below.
