Human Liver Lobule Diagram | Human Organ Anatomy

Biological diagram infographic titled "Human Liver Lobule". Center the composition around a clean LABELED DIAGRAM as an editorial-grade cross-section / histology-style schematic of a classic human hepatic lobule, shown as a roughly hexagonal structural unit with biologically accurate proportions for university undergraduate teaching. Use a central vein in the middle, portal triads at the corners, radiating plates of hepatocytes, sinusoids flowing inward, and bile canaliculi flowing outward; make the organization immediately legible and educational. Place exactly 7 labels arranged around the central diagram with thin leader lines, balanced spacing, and sharp readable text. Each label must include a short heading in English and a one-line function caption in English. Use directional arrows to distinguish blood flow toward the central vein and bile flow toward the portal triad. Include subtle legend cues for opposite flow directions if helpful. Labels to render exactly as follows: 1) "Central Vein" — "Collects blood from sinusoids and drains the lobule." 2) "Portal Triad" — "Contains a branch of the portal vein, hepatic artery, and bile duct." 3) "Sinusoids" — "Wide capillary channels that carry mixed blood toward the central vein." 4) "Hepatocyte Plates" — "Liver cells arranged in cords that process nutrients and synthesize proteins." 5) "Bile Canaliculi" — "Tiny channels that carry bile away from hepatocytes toward bile ducts." 6) "Kupffer Cells" — "Resident macrophages that remove debris and pathogens from blood." 7) "Space of Disse" — "Perisinusoidal space where exchange occurs between blood plasma and hepatocytes." Visual style: medical illustration (Netter-style), medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Color palette: monochrome scientific palette with grayscale, charcoal, soft slate, and muted silver shading; use tonal contrast to separate vessels, hepatocytes, and ducts while keeping the overall look refined, calm, and academic. Mood: precise, educational, tasteful, scientifically accurate, clean white background, 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.
