Detailed 3D model of the human respiratory system depicting smoker's lungs — including the oral cavity with teeth, larynx, trachea, and both lungs showing characteristic blackened tar/soot discoloration from long-term smoking exposure. The model provides an accurate visualization of the airway pathway from mouth to lungs alongside the pathological changes associated with chronic smoking.

Ideal for medical education, pulmonology teaching, anti-smoking health campaigns, pharmaceutical marketing, and respiratory disease explainer content (e.g., COPD, lung cancer awareness). All textures are baked (BaseColor, Roughness, Normal, Metallic, Displacement — PBR), making the model render-ready in Blender, Unity, Unreal Engine, or any PBR-compatible engine straight out of the box.

Formats included: .blend / .fbx / .obj / .gltfTextures: BaseColor, Roughness, Normal, Metallic, Displacement (baked, PBR)Type: Static (non-rigged), real-time and game-engine readyUse cases: Pulmonology education, anti-smoking health campaigns, respiratory pathology visualization, pharma marketing, medical animation
