Human Heart Anatomy Heart 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 tasteful branching callout layout around the central organ for scientific clarity. Show biologically accurate external and sectional heart anatomy with correct proportions, major chambers, valves, and vessels visible in a simplified modern textbook style for a curious enthusiast. Place 5 labeled parts around the heart with thin leader lines, sharp readable English text, and one-line function descriptions. 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." Use a balanced infographic composition with the heart centered and the 5 callouts evenly distributed around it in a subtle branching layout inspired by a tree diagram, but not a phylogenetic chart. Visual style: modern textbook, vibrant educational primary palette with reds, blues, yellow accents, clean white or very light neutral background, friendly educational mood, crisp vector shading, high contrast readability. Include small directional blood-flow arrows within the heart where helpful, but keep the focus on the 5 labeled structures. 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.
