Small intestine — glucose absorption — 45 minutes

A stylised teaching view of how glucose moves from the intestinal lumen toward the bloodstream in a representative healthy adult model.

Draws the villi as three receding rows. Turning it off flattens the field to a single labelled cross-section.

Stylised teaching diagram. Structure names label the drawn geometry; physiological statements appear only where a reviewed claim exists. Villus and particle counts are rendering budgets, not measurements. Rendered as the parametric tier-B scene on this device. Both tiers read the same geometry, and particle positions are a pure function of elapsed time and instance index, so scrubbing back to a moment reproduces it exactly on either.
