It highlights the branching structure of the bronchioles leading to the alveolar ducts and alveolar sacs, showcasing the intricate network where gas exchange occurs. The model effectively illustrates the thin-walled alveoli surrounded by capillaries, demonstrating how oxygen enters the bloodstream and carbon dioxide is removed during respiration.  \n\nDesigned for educational and clinical purposes, this model is an invaluable tool for studying pulmonary anatomy, understanding respiratory physiology, and visualizing conditions such as asthma, chronic obstructive pulmonary disease (COPD), emphysema, and pulmonary fibrosis. Ideal for medical professionals, educators, and students, it supports teaching, training, and patient education by offering a hands-on approach to exploring lung function and respiratory health.","imageAlt":"3D Model of Bronchioles and Alveoli Anatomy","url":"https://www.cgtrader.com/3d-models/science/medical/3d-model-of-bronchioles-and-alveoli-anatomy","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/u0gtdz5dq81e0jmb2vwuic2zxte6/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/3d-model-of-bronchioles-and-alveoli-anatomy-3d-model-5012221f4a.jpg","gridUrl":"https://media.cgtrader.com/variants/u0gtdz5dq81e0jmb2vwuic2zxte6/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/3d-model-of-bronchioles-and-alveoli-anatomy-3d-model-5012221f4a.webp","gridCandidates":[{"url":"https://media.cgtrader.com/variants/u0gtdz5dq81e0jmb2vwuic2zxte6/6a314ee64365e9a50cc847b264c0df438901d553e153606f3b641b8e48cb207e/3d-model-of-bronchioles-and-alveoli-anatomy-3d-model-5012221f4a.webp","width":306},{"url":"https://media.cgtrader.com/variants/u0gtdz5dq81e0jmb2vwuic2zxte6/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/3d-model-of-bronchioles-and-alveoli-anatomy-3d-model-5012221f4a.webp","width":612},{"url":"https://media.cgtrader.com/variants/u0gtdz5dq81e0jmb2vwuic2zxte6/fc2d80458320aed4ba722745705c02fa7f690497f6e3961b946cdf20c88a8c12/3d-model-of-bronchioles-and-alveoli-anatomy-3d-model-5012221f4a.webp","width":918}],"isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-models/science/medical/3d-model-of-bronchioles-and-alveoli-anatomy","isCgtVerified":false,"types":{"printReady":false,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":25,"name":".dae","is_native":false},{"id":21,"name":".blend","is_native":false},{"id":189,"name":".ply","is_native":false},{"id":12,"name":".obj","is_native":false},{"id":5,"name":".fbx","is_native":false},{"id":51,"name":".stl","is_native":false}],"categorySlug":"science","subcategorySlug":"medical","categoryTitle":"Science","subcategoryTitle":"Medical","schemaImageUrl":"https://img-new.cgtrader.com/items/5745582/5012221f4a/3d-model-of-bronchioles-and-alveoli-anatomy-3d-model-5012221f4a.webp","saleOffDiscount":50,"eligibleForSubscription":true,"subscriptionSubscribed":true,"subscriptionPotential":false,"subscriptionTierBand":"premium"}},{"id":"2245396","type":"listingItem","attributes":{"id":2245396,"title":"Realistic Human Bronchi Alveoli Anatomy","price":39.0,"description":"Originally modeled in Cinema 4D R 19\nFinal images rendered with Advanced Render\n\nAdvanced Format C4D\nOther Format OBJ STL 3DS FBX\n\nMaps for Realistic Human Bronchi Alveoli Anatomy\n\n- BaseColor\n- Metallic\n- Roughness\n- Normal\n- Ambient Occlusion\n\n\nSCALE:\n- Model at world center and real scale:\n       Metric in centimeter\n       1 unit = 1 centimeter\n\n\nTexture resolution 2048x2048\nTexture format PNG\n\n\nPoly Count :\nPolygon Count -
