Human Heart Anatomy Infographic with Labeled Blood Flow

Biological diagram infographic titled "Human Heart Anatomy" centered on a clean labeled pathway-flow diagram of the human heart, rendered as an editorial-grade anatomical cutaway showing blood flow input → output for a university undergraduate audience. Show a biologically accurate human heart in tasteful educational style, with clear internal chambers and major vessels, arranged vertically with flow cues and subtle directional arrows indicating deoxygenated blood entering and oxygenated blood leaving. Place 7 labeled components around the central diagram with thin leader lines; each component must have a short English heading in quotes and a one-line English function caption in quotes. Include these exact labels and captions: "Right Atrium" — "Receives deoxygenated blood returning from the body."; "Tricuspid Valve" — "Prevents backflow as blood moves into the right ventricle."; "Right Ventricle" — "Pumps deoxygenated blood to the lungs through the pulmonary artery."; "Pulmonary Artery" — "Carries deoxygenated blood from the heart to the lungs."; "Left Atrium" — "Receives oxygenated blood returning from the lungs."; "Left Ventricle" — "Pumps oxygenated blood into the aorta for systemic circulation."; "Aorta" — "Distributes oxygenated blood from the heart to the body." Add small input → output markers reading "Body → Heart", "Heart → Lungs", "Lungs → Heart", and "Heart → Body" placed along the pathway flow. Visual style: vintage 1900s scientific plate, natural anatomy tones palette, muted reds, warm ivory, sepia ink, soft blue-gray vessel accents, aged paper mood, refined engraved shading, elegant academic composition. Emphasize medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text sharp, high-contrast, and readable. Scientifically accurate proportions, biologically accurate anatomical naming, 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.
