Infographie anatomique du cœur humain, style schema cellule

Biological diagram infographic titled "Human Heart Anatomy" centered on a clean labeled cross-section of the human heart, editorial-grade anatomical cutaway showing the four chambers, major valves, and great vessels in scientifically accurate proportions, designed for a high school / general audience. Use a tasteful educational anatomy composition with the heart large in the center and 7 labels arranged evenly around the diagram with thin leader lines. Each label must contain a short English heading and a one-line English function caption. Include these exact labels and captions: "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."; "Tricuspid Valve" — "Prevents backflow from the right ventricle to the right atrium."; "Mitral Valve" — "Prevents backflow from the left ventricle to the left atrium."; "Aorta" — "Carries oxygen-rich blood from the heart to the body." Show clear internal structure, septum separation, valve placement, and vessel connections with medical-textbook clarity. Visual style: medical illustration (Netter-style), monochrome scientific palette, subtle grayscale shading, fine ink-like contour lines, soft tonal depth, calm academic mood, high legibility, vector-clean lines, no photographic textures, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text sharp and readable, no graphic gore, no real patient photos, no surgical blood, 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.
