This simulator visualizes how peristaltic waves move down the stomach, how retropropulsion grinds food against the pyloric sphincter, and how the enterogastric reflex slows emptying in response to fat, acid, or concentration in the duodenum.
Adjust the meal composition and duodenal feedback sensitivity to watch how the wave strength, pyloric opening, and overall emptying rate change in real time.
Sliders let you vary meal fat, protein, carbohydrate, and liquid content alongside duodenal sensitivity to see their combined effect on gastric emptying speed.
Only particles smaller than about 2 millimeters are typically allowed through the pyloric sphincter, meaning a single chunk of food may be churned and retropropelled dozens of times before it is small enough to pass.
