Human Heart Anatomy Heart Diagram Infographic

Biological diagram infographic titled "Human Heart Anatomy" featuring a central clean labeled anatomical diagram of the human heart in an educational comparison layout: show the exterior view beside a simplified cutaway cross-section of the same heart for structure comparison, centered on the page. Render an editorial-grade anatomical illustration with scientifically accurate proportions, tasteful educational presentation, and no gore. Place 9 labels arranged evenly around the central diagram with thin leader lines pointing clearly to the correct structures; each label must include a short heading in English and a one-line function description in English. Use these exact on-image labels and captions: "Aorta" — "Carries oxygen-rich blood from the heart to the body."; "Superior vena cava" — "Returns oxygen-poor blood from the upper body to the right atrium."; "Right atrium" — "Receives oxygen-poor blood returning from the body."; "Tricuspid valve" — "Prevents backflow from the right ventricle into the right atrium."; "Right ventricle" — "Pumps oxygen-poor blood to the lungs."; "Pulmonary artery" — "Transports oxygen-poor blood from the heart to the lungs."; "Left atrium" — "Receives oxygen-rich blood coming from the lungs."; "Mitral valve" — "Prevents backflow from the left ventricle into the left atrium."; "Left ventricle" — "Pumps oxygen-rich blood into the aorta for the body." Add a small unobtrusive legend using blue and red flow accents to distinguish oxygen-poor and oxygen-rich blood, with sharp readable typography sized for a curious enthusiast audience. Visual style: colorful kids-book, friendly but medically accurate, cool clinical blues palette with cyan, teal, navy, soft red accents for oxygenated flow, balanced white background, approachable and clean mood. Include 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.
