Answer:
The ileum has a large number of villi and microvilli to increase the surface area for absorption of digested food. The ileum has a thin layer of cells for easy and fast diffusion of digested food. The blood capillaries also promote a steep diffusion gradient for efficient absorption of the digested food substances.
Function. The main function of the ileum is to absorb vitamin B12, bile salts, and whatever products of digestion were not absorbed by the jejunum. The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface.
