Human Heart Anatomy Infographic | phase diagram of co2

Biological diagram infographic titled "Human Heart Anatomy" centered on a clean labeled cross-section of the human heart, editorial-grade anatomical cutaway for university undergraduate teaching, showing biologically accurate proportions of chambers, valves, and major vessels. Use a medical illustration (Netter-style) approach with monochrome scientific palette in grayscale with subtle tonal variation, calm academic mood, crisp high-contrast typography, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Arrange 7 labels evenly around the central heart diagram with thin leader lines pointing precisely to structures; each label must include a short heading in English and a one-line function caption in English. Labels to render exactly as: "Right Atrium" — "Receives deoxygenated blood from the venae cavae."; "Right Ventricle" — "Pumps deoxygenated blood to the lungs through the pulmonary trunk."; "Left Atrium" — "Receives oxygenated blood from the pulmonary veins."; "Left Ventricle" — "Pumps oxygenated blood into the aorta for systemic circulation."; "Tricuspid Valve" — "Prevents backflow from the right ventricle into the right atrium."; "Mitral Valve" — "Prevents backflow from the left ventricle into the left atrium."; "Aorta" — "Carries oxygenated blood from the heart to the body." Show internal septum and vessel continuity clearly but do not label extra parts beyond the 7 requested labels. Make all text sharp, readable, and professionally typeset. Educationally tasteful human anatomy only, no graphic gore, no surgical blood, no real patient photographs, 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.
