Kidney Nephron Anatomy Infographic with Labeled Structures

Biological diagram infographic titled "Kidney Nephron Anatomy" centered on a clean labeled cross-section of a biologically accurate human kidney nephron, editorial-grade anatomical illustration for a medical professional audience. Show a single nephron in clear educational proportion: renal corpuscle with glomerulus inside Bowman's capsule, proximal convoluted tubule, loop of Henle descending limb and ascending limb, distal convoluted tubule, collecting duct, associated afferent arteriole, efferent arteriole, and peritubular capillaries / vasa recta. Arrange 9 labels evenly around the central diagram with thin leader lines pointing precisely to each structure; each label must include a short English heading and a one-line English function caption. Use medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Visual style: minimal flat scientific. Color palette: forest green & earth palette with muted greens, moss, sage, warm beige, clay, and soft brown accents. Mood: calm, precise, professional, educational. All text sharp, high-contrast, and readable.

Include these exact on-image labels and captions:
1. "Glomerulus" — "Filters blood plasma into the nephron."
2. "Bowman's capsule" — "Collects the filtrate from the glomerulus."
3. "Afferent arteriole" — "Delivers blood into the glomerular capillaries."
4. "Efferent arteriole" — "Carries blood away after filtration."
5. "Proximal convoluted tubule" — "Reabsorbs water, ions, and nutrients."
6. "Loop of Henle" — "Creates the osmotic gradient for urine concentration."
7. "Distal convoluted tubule" — "Fine-tunes ion balance and pH."
8. "Collecting duct" — "Receives tubular fluid and concentrates urine."
9. "Peritubular capillaries / vasa recta" — "Return reabsorbed substances to the blood."

Render as a tasteful educational human anatomy diagram, no gore, no bloodshed, no surgical imagery, no real patient photos, no cruelty imagery. Keep the composition centered on the nephron cross-section with clean negative space and balanced label placement. Scientifically accurate labeling and proportions. 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.
