Magnified Pulmonary Alveoli

This anatomical model serves as a visual aid for teaching hygiene and physiology in middle schools. It helps the students to understand the distribution of bronchioles in lungs being divided into terminal bronchioles and their relations with pulmonary alveoli.

The model shows the small branches of principal bronchus:

1. Section of bronchiole of no cartilage.
2. The relation between pulmonary alveoli and terminal bronchiole.
3. The structure of alveolar sac and alveolar duct.
4. The capillary rete in the alveolar sapta.
