human respiratory system 3d model

Create a highly realistic 3D medical anatomical animation of the human respiratory system, specifically demonstrating the mechanics of breathing during inhalation and exhalation. CAMERA AND ANATOMY: Show a transparent anatomical view of the human upper torso from the front, centered on the chest. Clearly visualize both lungs, trachea, bronchi, rib cage, and diaphragm. Keep the anatomy medically accurate, symmetrical, clean, and easy to understand. Use a professional medical-education visualization style. SCENE 1 — INHALATION: Slowly animate air entering through the upper airway and traveling down the trachea into the bronchi and lungs. Show the lungs gradually expanding in volume. At the same time, the diaphragm contracts and moves downward, becoming flatter. The rib cage expands outward and slightly upward. Use subtle animated blue airflow arrows moving inward toward the lungs. Make the movement smooth, synchronized, and physiologically accurate. SCENE 2 — EXHALATION: Transition sm
