Alveoli Gas Exchange Cycle Infographic for Kids

Biological diagram infographic titled "Alveoli Gas Exchange Cycle" centered on a clean labeled diagram of human respiratory alveoli, shown as an educationally tasteful isometric 3D close-up of an alveolar sac with surrounding capillaries, arranged as a circular cycle with directional arrows to explain breathing and gas exchange for kids ages 8-12. Place 5 labeled components evenly around the central diagram with thin leader lines, short English labels, and one-line English function captions. Labels to render exactly as: "Air In" — "Oxygen-rich air enters the alveoli during inhalation."; "Alveoli" — "Tiny air sacs where gases move between air and blood."; "Capillaries" — "Small blood vessels that carry blood around each alveolus."; "Oxygen to Blood" — "Oxygen passes through the alveolar wall into the blood."; "Carbon Dioxide Out" — "Carbon dioxide moves from blood into the alveoli to be exhaled." Include circular flow arrows linking inhalation, gas exchange, blood transport, carbon dioxide return, and exhalation. Keep anatomy biologically accurate with clear alveolar walls, bronchiole connection, and capillary network in correct proportions. Use simple kid-friendly educational composition, soft pastel palette, gentle pinks, light blues, mint, lavender, and warm cream, calm and friendly mood, sharp readable typography, uncluttered background, subtle legend icons if needed, 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.
