Human Circulatory System Cycle Infographic Posters

Biological diagram infographic titled "Human Circulatory System Cycle" centered on a clean labeled circular flow diagram of the human circulatory system, designed for university undergraduate audience. Show an educationally tasteful isometric 3D human torso with heart and major vessels simplified into a circular circulation pathway, with clear directional arrows indicating blood flow through pulmonary and systemic circuits. Arrange exactly 5 labeled components around the central diagram with thin leader lines; each label must include a short heading in English and a one-line function description in English. Labels to render exactly as: "Heart" — "Pumps blood through pulmonary and systemic circulation."; "Lungs" — "Exchange carbon dioxide for oxygen in pulmonary capillaries."; "Arteries" — "Carry blood away from the heart under pressure."; "Capillaries" — "Allow exchange of gases, nutrients, and wastes with tissues."; "Veins" — "Return blood back to the heart at lower pressure." Include directional arrows around the circular cycle to show: heart -> arteries -> capillaries -> veins -> heart, with pulmonary circulation visually linked between heart and lungs. Add subtle input-output style markers for "Oxygenated blood" and "Deoxygenated blood" in English. Visual style: isometric 3D, pastel soft palette, calm academic mood, balanced composition, sharp readable typography, scientifically accurate proportions and biologically accurate anatomical naming, 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.
