Art style: 3D Medical Animation.
An extreme close-up of a narrowing anatomical airway, a pink fleshy passage constricting sharply toward the center. A stark red warning wash begins seeping inward from all four frame edges, vignetting the scene. Centered composition, straight-on view, shallow depth of field on the airway walls. Tense, urgent lighting with a harsh crimson glow bleeding from the borders against warm interior tissue tones. Alarming, high-stakes atmosphere. Dominant palette of deep red, inflamed pink, and dark shadow.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Medical Animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Medical Animation". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "3D Medical Animation" idiom, not in any other medium.
