Liver Lobule Structure Infographic | Human Anatomy Diagram

Biological diagram infographic titled "Liver Lobule Structure" centered on a clean labeled diagram of a human classical liver lobule shown as an editorial-grade hexagonal cross-section, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Render a biologically accurate educational anatomy diagram for a high school/general audience in medical illustration (Netter-style), monochrome scientific palette with grayscale, charcoal, soft slate, and subtle ink shading, calm academic mood, sharp readable typography, tasteful human anatomy, no gore. Show the central vein in the middle, portal triads at the lobule corners, hepatocyte plates radiating inward, sinusoids flowing toward the center, Kupffer cells along sinusoid walls, bile canaliculi between hepatocytes flowing outward, and a clear directional indication of blood flow versus bile flow. Arrange exactly 7 labels 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. Use these exact on-image labels and captions: "Central vein" — "Collects blood from sinusoids and drains the lobule."; "Portal triad" — "Contains a branch of the portal vein, hepatic artery, and bile duct."; "Hepatocyte plates" — "Liver cells process nutrients, detoxify blood, and make bile."; "Sinusoids" — "Wide capillaries where portal and arterial blood mix and flow inward."; "Kupffer cells" — "Resident macrophages that remove debris and pathogens from blood."; "Bile canaliculi" — "Tiny channels that carry bile away from hepatocytes toward bile ducts."; "Blood flow / bile flow" — "Blood moves to the central vein while bile moves toward the portal triad." Include subtle legend arrows for inward blood flow and outward bile flow, with clean spacing and balanced composition. 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.
