Human Circulatory System Overview Anatomy Infographic

Biological diagram infographic titled "Human Circulatory System Overview" centered on a clean labeled diagram of the human circulatory system in an editorial-grade anatomical layout, adapted to an evolutionary-tree composition: a central full-body simplified human figure with the heart at the trunk and major blood vessels branching outward like a clear scientific tree, with 5 labeled components arranged around the central diagram and connected by thin leader lines. Show biologically accurate proportions and anatomically correct vessel pathways, educational and tasteful, high school textbook friendly. Label exactly these 5 parts with sharp readable English text and one-line function captions: "Heart" — "Pumps blood through pulmonary and systemic circuits."; "Aorta" — "Carries oxygen-rich blood from the left ventricle to the body."; "Vena cava" — "Returns oxygen-poor blood from the body to the right atrium."; "Pulmonary arteries" — "Carry oxygen-poor blood from the heart to the lungs."; "Pulmonary veins" — "Bring oxygen-rich blood from the lungs back to the heart." Include subtle branching hierarchy cues to fit the evolutionary tree archetype while preserving circulatory accuracy, with clear arterial and venous differentiation. Visual style: modern textbook, vibrant educational primary palette with red for arteries, blue for veins, warm neutral body tones, soft off-white background, crisp infographic layout, balanced whitespace, confident educational mood. Include a small unobtrusive legend for oxygen-rich vs oxygen-poor blood in English. Emphasize 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.
