Kidney Nephron Anatomy Infographic with Labeled Diagram

Biological diagram infographic titled "Kidney Nephron Anatomy" centered on a clean labeled cross-section of a human kidney nephron, showing a biologically accurate editorial-grade anatomical diagram with tasteful educational rendering for a curious enthusiast. Main composition: one enlarged nephron unit with renal corpuscle and tubule segments clearly distinguished, laid out vertically and proportionally, with 9 labels arranged around the central diagram using thin leader lines. Each label must include a short heading in English and a one-line function caption in English. Include these exact labels and captions: "Afferent arteriole" — "Delivers blood to the glomerulus for filtration."; "Glomerulus" — "Capillary knot that filters water and small solutes."; "Bowman's capsule" — "Collects the filtrate from the glomerulus."; "Proximal convoluted tubule" — "Reabsorbs most water, ions, and nutrients."; "Loop of Henle" — "Creates a concentration gradient to conserve water."; "Distal convoluted tubule" — "Fine-tunes ion balance and pH regulation."; "Collecting duct" — "Carries urine onward and adjusts final water reabsorption."; "Peritubular capillaries" — "Return reabsorbed substances to the bloodstream."; "Efferent arteriole" — "Drains blood away from the glomerulus." Add a small unobtrusive legend with simple color coding for blood flow, filtrate flow, and tubule walls. Use minimal flat scientific visual style, forest green and earth palette, soft beige background, calm educational mood, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All labels must be sharp, readable, and evenly spaced, with thin precise callout lines and consistent typography. Scientifically accurate anatomical naming and proportions, no graphic gore, no real patient photos, no surgical blood, no cruelty imagery. 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.
