Human Heart Anatomy Anatomical Diagram Infographic

Biological diagram infographic titled "Human Heart Anatomy" centered on a clean labeled diagram of the human heart as an editorial-grade anatomical cross-section, adapted from the requested evolutionary tree archetype into a scientifically accurate central educational anatomy diagram for a curious enthusiast. Show the heart front-facing with visible chambers, major vessels, and valves in tasteful cutaway form, with 5 labeled parts arranged evenly around the central diagram using thin leader lines. Each label must include a short heading in English and a one-line function description in English. Labels to render exactly as: "Right Atrium" — "Receives oxygen-poor blood from the body."; "Right Ventricle" — "Pumps oxygen-poor blood to the lungs."; "Left Atrium" — "Receives oxygen-rich blood from the lungs."; "Left Ventricle" — "Pumps oxygen-rich blood to the body."; "Aorta" — "Carries oxygen-rich blood from the heart to the body." Include subtle directional blood-flow arrows within the heart for clarity, but keep the layout anatomy-focused rather than a pathway. Use modern textbook visual style, vibrant educational primary palette with reds, blues, yellow accents, clean white background, balanced composition, friendly scientific mood, sharp readable typography, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Ensure biologically accurate proportions and anatomical naming, educationally tasteful presentation, no graphic gore, no surgical blood, no real patient photos, no cruelty imagery, no watermarks. 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.
