Digestive / VISUAL EXPLAINER
Why Does Blood from Your Gut Visit the Liver First?
Portal blood brings many absorbed nutrients from digestive organs to the liver. Portal and hepatic arterial branches feed sinusoidal channels, and hepatic veins carry blood onward toward the vena cava; most long-chain dietary fat initially follows lymph.

What the illustration shows
Navy-and-gold poster titled Why Does Blood from Your Gut Visit the Liver First? An abdominal cutaway shows a purple portal vein rising from intestine into liver, a separate red hepatic artery, and a separate blue hepatic-vein network draining upward into the inferior vena cava. Arrows on main trunks indicate inflow and outflow. A schematic liver lobule labels portal and arterial branches, purple sinusoids between orange cells, and central vein leading toward hepatic veins. Text explains nutrient-carrying portal blood, dual inflow to sinusoids, hepatic venous outflow, and that most long-chain dietary fat starts through lymph. Gold AllHumanBody.com and project slogan appear below.
How to interpret this poster
- Vascular networks are exposed and displaced for clarity, not a surgical segmental map or literal surface vessels.
- Colors distinguish routes, not oxygen-free blood; no fixed flow fractions or perfect toxin-removal claim.
- The lobule is schematic and does not teach bile drainage.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
