- Absorption in the small intestine
- How soluble products are absorbed into the body
- Villi and microvilli
- Folded finger like projections
- Thin walls lined with epithelial cells
- Rick network of capillaries on the other side
- Increase surface area and increase rate of diffusion
- Situated between the interface between the lumen of intestines and the blood and other tissues
- Adapted for absorption of products of digestion
- How they increase rate of diffusion
- Increase surface area
- Thin walls- reducing diffusion pathway
- Able to move - maintain diffusion gradient
- Supplied with blood vessels - maintain diffusion gradient
- Villi and microvilli
- Role of active transport
- Not all available glucose can be absorbed by diffusion
- Glucose is absorbed by active transport
- How soluble products are absorbed into the body
