The alveolar magnification model is an intuitive teaching tool used for respiratory system teaching and demonstration. By magnifying and presenting the tiny alveolar structure, it helps learners clearly understand its morphological characteristics and gas exchange mechanism. Models typically display alveolar sacs, alveolar ducts, capillary networks and thin-walled structures, intuitively demonstrating the exchange process of oxygen and carbon dioxide between the alveoli and capillaries, making abstract physiological concepts easier to understand.

In medical school anatomy and physiology courses, this model is used to explain respiratory function, lung compliance and pathological changes, such as emphysema, inflammation and ventilation/gas exchange disorders, etc. In clinical teaching, it can assist in explaining the principles related to mechanical ventilation, inhalation therapy and respiratory rehabilitation, helping medical staff and patients establish a clearer understanding of lung function. In addition, alveolar magnification models are also frequently used in popular science publicity, school teaching and health education activities, vividly demonstrating the impact of factors such as smoking and air pollution on alveolar structure. They are efficient and important display tools in respiratory system teaching.
