Human Circulatory System Cycle Infographic for Kids

Biological diagram infographic titled "Human Circulatory System Cycle" centered on a clean labeled circular flow diagram of the human circulatory system, designed for kids ages 8–12, with directional arrows showing blood flow in a simple continuous loop. Use an educationally tasteful human anatomy illustration with a simplified torso and heart-lung-body circulation, scientifically accurate proportions and biologically accurate naming. Arrange exactly 5 labeled components around the central diagram, each with a thin leader line, a short label in English, and a one-line function description in English. Labels to render exactly as: "Heart" — "Pumps blood through the body."; "Lungs" — "Add oxygen to blood and remove carbon dioxide."; "Arteries" — "Carry blood away from the heart."; "Capillaries" — "Exchange oxygen, nutrients, and wastes with tissues."; "Veins" — "Carry blood back to the heart.". Show the cycle clearly with arrows in this order: Heart → Lungs → Heart → Arteries → Capillaries → Veins → Heart, simplified into a circular educational flow. Visual style: isometric 3D, pastel soft palette, friendly classroom infographic, bright but gentle colors, approachable and simple mood, all text sharp and readable. Include subtle legend icons for oxygen-rich and oxygen-poor blood using soft red and soft blue. Maintain 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.
