Neuroanatomy Poster Style Human Circulatory System Infographic

Biological diagram infographic titled "Human Circulatory System" centered on a clean labeled anatomical diagram of the human torso in frontal view, showing the heart and major blood vessels with simplified internal cross-section emphasis, educationally tasteful and scientifically accurate proportions. Create an editorial-grade anatomy infographic for a curious enthusiast: minimal flat scientific style, forest green and earth-tone palette, calm academic mood, balanced negative space, crisp typography, sharp readable labels. Arrange 9 labels evenly around the central 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 biologically accurate anatomical naming. Labels to render exactly as: "Heart" — "Muscular pump that drives blood through pulmonary and systemic circuits."; "Aorta" — "Largest artery carrying oxygenated blood from the left ventricle to the body."; "Superior vena cava" — "Returns deoxygenated blood from the head and upper body to the right atrium."; "Inferior vena cava" — "Returns deoxygenated blood from the lower body to the right atrium."; "Pulmonary arteries" — "Carry deoxygenated blood from the right ventricle to the lungs."; "Pulmonary veins" — "Bring oxygenated blood from the lungs to the left atrium."; "Carotid arteries" — "Deliver oxygenated blood to the head and brain."; "Renal vessels" — "Supply and drain the kidneys, supporting blood filtration and fluid balance."; "Femoral vessels" — "Transport blood to and from the lower limbs." Include subtle distinction between arteries and veins using two harmonized tones within the forest green & earth palette while remaining flat and minimal; show directional flow with small unobtrusive arrows near major vessels. Add a small clean legend indicating artery and vein colors in English. Composition should resemble a refined science poster, not a neuroanatomy poster, with 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.
