A 4 stage cross-section of the bronchus, this Bronchus Anatomy Model demonstrates the tissue changes occurring in asthma and chronic bronchitis. The 4-stages shown are: normal bronchus, hypersecretion of the mucous gland, swelling with lymphoid aggregations and smooth-muscle spasm.  Stages rotate on a labeled hinge and the model comes with a helpful handle and education card.  

The 4-Part Bronchus Model depicts:

• Cartilage
• Mucous glands and plugs
• Spiraling smooth muscles
• Fibroelastic connective tissue
• Epithelial layers of the bronchus
