Key Stage 3
Meaning
Villi are small folds in the wall of the small intestine that increase its surface area.
Adaptations of Villi
- Villi have a wall only one cell thick so the [nutrient]]s only have a short distance to diffuse into the blood.
- Villi capillaries inside them for a good blood supply to allow for quick diffusion into the blood.
- Villi have a large surface area to allow quicker diffusion.
- The cells in the walls of the villi have microvilli to provide an even bigger surface area for quicker diffusion.
About Villi
- Villi cover inside of the small intestine.
- Villi increase the surface area of the small intestine.
