Flow Behavior of Digesta and the Absorption of Nutrients in the Gastrointestine

Digesta flow-behavior types in the intestinal lumen, such as turbulent and laminar flow, should define modes of digestion and absorption. This review presents a simulation of flow behavior in the intestinal lumen and discusses the behavior of nutrients and enzymes in the intestinal lumen under laminar-flow conditions. The significance of digesta viscosity for glucose and water absorption and digestion and fermentation in the intestine is also discussed.
