Educational infographic poster titled "How Your Lungs Work" in portrait layout, designed for kids ages 8-12, with sharp readable text labels in clean sans-serif typography. Create a medicine/anatomy themed educational infographic with 6 clearly numbered components arranged in a top-to-bottom sequence, using bold headings, one-line captions, and precise isometric 3D visual elements. Use connecting arrows and dotted flow lines between each numbered section, with clear sequence numbers in yellow circles. Visual style: isometric 3D, high-contrast yellow and navy palette, friendly, smart, approachable, kid-safe, clean educational mood. Include magazine-grade editorial illustration, vector-clean lines, no photographic textures. Avoid graphic medical content, keep explanations conceptual.

1. heading: "1. Nose and Mouth"; caption: "Air enters your body through the nose or mouth."; visual: isometric cutaway of a simplified child-safe head profile showing nose, mouth, and a bright yellow airflow arrow moving inward, with tiny clean air icons.

2. heading: "2. Windpipe"; caption: "Air travels down the windpipe toward the chest."; visual: isometric transparent neck and upper chest with a highlighted trachea tube in yellow, shown as a smooth vertical passage, with a downward arrow inside the tube.

3. heading: "3. Bronchi"; caption: "The windpipe splits into two main air branches."; visual: isometric chest cutaway showing the trachea dividing into left and right bronchi like a Y-shaped tube, with split arrows pointing to both lungs.

4. heading: "4. Lungs"; caption: "The lungs fill up like soft balloons with each breath in."; visual: isometric pair of simplified lungs in navy with yellow glow edges, slightly expanded, with small inhale arrows showing chest expansion.

5. heading: "5. Tiny Air Sacs"; caption: "Tiny air sacs pass oxygen into the blood."; visual: zoom-in circular callout diagram of alveoli as grape-like sacs connected to tiny red-and-blue blood vessels, with small arrows showing oxygen moving across.

6. heading: "6. Breathing Out"; caption: "Used air leaves the body when the lungs relax."; visual: isometric lungs gently shrinking with outward arrows moving back up through bronchi, trachea, and out the mouth and nose, plus a simple exhale symbol.

Add a small side legend panel with exact labels: "Air In" and "Air Out" and "Oxygen" and "Blood Vessels" using matching yellow/navy icon keys. Background should be light neutral with navy structure lines and bold yellow highlights for arrows, numbers, and key anatomy paths. Composition should be tidy, evenly spaced, and easy to follow for children, with each numbered block clearly separated but visually linked in one continuous flow. No real-brand logos, no copyrighted characters, no identifiable people, no clutter.

All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
