Blood Components Educational Infographic Diagram

Biological diagram infographic titled "Blood Components" centered on a clean labeled diagram of a human blood sample shown as an editorial-grade educational cross-section: a large circular cutaway of flowing blood inside a vessel lumen, with plasma as the background fluid and suspended formed elements shown in scientifically accurate proportions. Surround the central diagram with 9 clearly separated callouts connected by thin leader lines. Each callout must contain a short English heading and a one-line English function caption. Use biologically accurate anatomical naming and high-school-friendly clarity. Labels to include exactly: 1) "Plasma" — "Liquid matrix that transports cells, nutrients, hormones and waste." 2) "Erythrocyte" — "Biconcave red blood cell that carries oxygen and some carbon dioxide." 3) "Leukocyte" — "White blood cell that helps defend the body against infection." 4) "Platelet" — "Cell fragment that helps start blood clotting and vessel repair." 5) "Hemoglobin" — "Iron-containing protein inside erythrocytes that binds oxygen." 6) "Neutrophil" — "Granular leukocyte that engulfs and destroys many bacteria." 7) "Lymphocyte" — "Leukocyte that supports targeted immune responses and immune memory." 8) "Monocyte" — "Large leukocyte that can become a macrophage in tissues." 9) "Fibrinogen" — "Plasma protein that is converted into fibrin during clot formation." Render the erythrocytes as numerous red-toned biconcave discs, a few leukocyte subtypes with distinct simplified nuclei, tiny platelets as small fragments, and subtle plasma proteins indicated cleanly without clutter. Composition should be balanced and readable, with labels arranged evenly around the diagram. Visual style: minimal flat scientific, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Color palette: forest green and earth palette with muted reds, olive, moss, tan, cream, and soft brown accents. Overall mood: calm, educational, precise, tasteful, accessible for general audiences. Include a small unobtrusive legend area only if needed for clarity, keep all text sharp and readable, white or light neutral background, no graphic medical gore, no real patient photos, no surgical blood, no cruelty imagery, no decorative clutter. 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.
