Hover organs for details · Choose food type before dropping
Mouth: Mechanical + salivary amylase (starch→maltose, pH 7). Esophagus: Peristalsis pushes food. Stomach: Pepsin breaks protein (pH 2, HCl). Small intestine: Bile + pancreatic enzymes, nutrient absorption via villi (pH 8). Large intestine: Water absorption, bacteria. Food particles shrink as nutrients are extracted.
