Ideal for pulmonologists, respiratory therapists, and patient education programs that need a multi-piece, enlarged airway reference for explaining the structural effects of COPD on bronchial and alveolar tissue.

Enlarged, four-piece model showing the effects of COPD on the bronchus and alveoli. The bronchus cross-section shows a healthy bronchus and the mucus hypersection resulting from COPD. A healthy aveoli is contrasted with an emphysema aveoli with cross-section showing wall destruction and decreased, larger alveolar ducts.

The removable reference card slots into the base.
