The laryngal-cardiopulmonary model is a comprehensive teaching model integrating the structures of the larynx, heart and lungs, and is widely used in clinical teaching and medical popular science scenarios.

Firstly, this model can visually present the three-dimensional structure of the upper respiratory tract, trachea, bronchi and lung lobes. At the same time, by integrating cardiac anatomy, it enables learners to understand the physiological connection between the respiratory and circulatory systems.

Secondly, it is used in classroom teaching and practical training demonstrations, which can help students observe the glottis, laryngeal cartilage, tracheal branches, alveolar positions, as well as the structural layout of the atria and ventricles, and enhance spatial cognition.

Secondly, in the popularization of health promotion in the medical field, this model can be used to explain to the public the hazards of smoking, airway obstruction, and the operation of heart and lung functions, making complex principles easy to understand.

In addition, the laryngal-cardiopulmonary model is often used in nursing and first aid training to explain the basic knowledge of respiratory disorders, the mechanisms of cardiopulmonary diseases, and airway management. It is a commonly used visual auxiliary tool in medical colleges and hospitals for teaching and health education.
