Human Heart Anatomy Infographic with Labeled Cross-Section

Biological diagram infographic titled "Human Heart Anatomy" centered on a clean labeled cross-section of the human heart, editorial-grade and biologically accurate for university undergraduate education. Render a tasteful anatomical cutaway showing the four chambers, major valves, septum, and great vessels in correct proportion, with the central heart dominating the composition. Place 7 labels evenly around the diagram with thin leader lines pointing precisely to structures; each label must include a short heading in English and a one-line function description in English. Use a monochrome scientific palette with grayscale tones, subtle shading, high contrast linework, and a calm academic mood. Visual style: medical illustration (Netter-style), medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Include sharp readable typography, clean spacing, and a minimal legend style if needed. Labels to render exactly as follows: "Right Atrium" — "Receives deoxygenated blood from the body."; "Right Ventricle" — "Pumps deoxygenated blood to the lungs."; "Left Atrium" — "Receives oxygenated blood from the lungs."; "Left Ventricle" — "Pumps oxygenated blood into systemic circulation."; "Interventricular Septum" — "Separates the right and left ventricles."; "Tricuspid Valve" — "Prevents backflow from the right ventricle to the right atrium."; "Aorta" — "Carries oxygenated blood from the heart to the body." Show subtle directional blood-flow arrows within the heart chambers and vessels for clarity, but keep the diagram primarily anatomical rather than pathway-based. Scientifically accurate labeling and proportions, educationally tasteful, no graphic gore, no surgical blood, no real patient photographs, 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.
