TEACHING AIDS: Transparent lung segment model is a simulated human anatomy teaching model. From the outside to the inside of the transparent lung shell, the distribution of the right lung, left lung, trachea and bronchi, and bronchial tree can be seen HIGH DEGREE OF SIMULATION: Lung model 3D presents the structure of the bronchial tree of the lung segment at a 2X magnification scale, and accurately restores the shape and position of the bronchial tree of the lung segment STRONG DISPLAYABILITY: Anatomical lung model can be placed on the display cabinet or on the desktop as a reference for teaching and learning, enabling the observer to understand its details more clearly TRANSPARENT DESIGN: Lung model for education is made of transparent PVC materials, so that observers can intuitively observe and learn the internal structure of the bronchial tree of the lung segment APPLICATION: Transparent human lung model is suitable for medical schools, hospitals, scientific research institutions and other places, for students, doctors and researchers
