- Realistic anatomical details: clearly defined bronchial tree, membranes, and lobes provide an accurate reference to help students visualize the respiratory system in science, biology labs, or healthy learning environments - Durable design: scratch-resistant materials, safe for frequent handling, and built for long-term use in educational environments including primary schools, colleges, and medical training programs - Interactive learning function: simulates the expansion and contraction of the lungs to demonstrate breathing mechanics, offering easy-to-understand visual movement for classroom instruction, science labs, or biology workshops - Education tool: complements textbooks and charts with a tangible 3D view of the lung structure, making it suitable for any biology collection or medical training program - Practical applications: - Use in high school biology lessons to demonstrate lung anatomy and breathing - Use in college physiology labs to study respiratory mechanics and cardiopulmonary relationships - Use in nursing, paramedic, or respiratory therapy training programs to reinforce anatomy and breathing concepts
