Dynamic demonstration structure: Shows the full breathing process of the lungs through practice-oriented mobility. Enables a tactile experience of lung function with visual support to foster intuitive understanding of anatomical processes. Durable construction: Specially developed material combination blends soft grip with exceptional form stability. Withstands intensive practice without signs of wear, delivering consistently accurate representation of anatomical breathing movements. Logic training and motor skills: Builds analytical thinking and precise movement sequences at the same time. Promotes holistic development by meaningfully linking mental concepts with physical actions. Interactive study object: The didactically optimized model supports competence development in human biology through its user-friendly construction, creating motivating learning situations that support sustainable knowledge retention. Use scenarios and applications - Classroom demonstration: In biology or anatomy lessons, the model is used to illustrate inhalation and exhalation, allowing students to physically engage with the lung motion while observing the visual cues for better comprehension of the breathing cycle. - Self-guided study and exam preparation: Students can connect theoretical concepts of respiratory physiology with hands-on practice, reinforcing memory through manipulation and observation of the breathing process. - Patient education and health coaching: Instructors or healthcare educators use the model to explain respiratory mechanics and breathing techniques to patients, improving understanding of how the lungs function during various activities or therapies.
