The villi percentage of Cell Surface Area is fifty. The radius is times one. The cell shape has a ratio of ten to one. The number of dimples is forty. the dimple percentage of cell surface area is also one. The highest rate of diffusion is at 4.64. This is the most effective shape and size of a cell to maximize diffusion in cells because it has a high surface area while maintaining a small volume. As moleculer size increases, diffusion rates decrease. This is why villi increase the surface area of the intestine to increase absorption of nutrients.
