Anatomy of the Human Respiratory Cycle

Image Prompt: Full sagittal cross-section human head showing brain, nasal cavity, mouth, tongue, throat, upper respiratory system. Anatomically accurate educational style. White airflow streams enter through nose. Natural tissue colors (pink, red, beige), gray-pink brain. Dark background. Hyper-realistic 3D medical animation. Video Prompt: A calm, deep voice-over narrates: “The entire nasal system works in harmony to prepare the air we breathe for the delicate tissues of the lungs. From the moment air enters the nostrils, it is filtered, warmed, humidified, and tested for potential threats.” Animated airflow streams flow smoothly through nasal passages into throat and lungs. Slow camera orbit around head profile revealing 3D depth of structures. Breathing cycle shown with air moving through complete system. Elegant, sweeping camera movement.
