Simple Cell Structure Diagram: Healthy vs Inflamed Alveoli

Biological diagram infographic titled "Alveoli: Healthy vs Inflamed Air Sacs" featuring a central clean labeled comparison diagram of two respiratory alveoli cross-sections side by side, one healthy alveolus and one inflamed mucus-filled alveolus, educational and scientifically accurate, designed for kids ages 8-12. Center the composition around an editorial-grade anatomical comparison with large simplified shapes, clear differences, and tasteful textbook presentation. Arrange 9 labeled parts around the central diagram with thin leader lines; each label must include a short heading in English and a one-line function description in English. Labels to include: "Alveolus" — "Tiny air sac where gas exchange happens."; "Bronchiole" — "Small airway that brings air to the alveoli."; "Alveolar Wall" — "Very thin wall that lets gases move across."; "Capillaries" — "Tiny blood vessels that carry blood around the air sac."; "Oxygen In" — "Oxygen moves from the alveolus into the blood."; "Carbon Dioxide Out" — "Carbon dioxide moves from the blood into the alveolus."; "Elastic Fibers" — "Help the alveolus stretch and spring back."; "Mucus" — "Extra mucus can block airflow and reduce gas exchange."; "Inflammation" — "Swelling makes the air sac work less well." Show subtle arrows to compare easy airflow and gas exchange in the healthy alveolus versus reduced airflow and reduced gas exchange in the inflamed alveolus. Use a colorful kids-book visual style, cool clinical blues palette with gentle cyan, teal, sky blue, and soft navy accents, friendly educational mood, simplified but biologically accurate proportions, sharp readable typography, balanced spacing, uncluttered white or very pale blue background, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. 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 graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
