To increase the surface area of which the products of digestion can diffuse across (into the blood)
We have a lot of villis inside our villis because we need them to help conrtol our blood.
Is it true that intestinal villi contains capillaries and lacteals important for chemical digestion?
Villi (Sing. Villus)
Wherever capillaries are found, these are places where nutrients and wastes are exchanged.
Lacteals.
capillaries in the villi
the villi are tiny finger-like protrusions lining the small intestines. Digested food passes the villi and broken-down food molecules are absorbed through a wall of cells, and into tiny blood vessels inside the villi called capillaries. Nutrient filled blood from the capillaries joins the main bloodstream in veins around the intestines, ready to be used in other parts of the body. Having villi lining the intestines ensures maximum absorption of nutrients through a huge surface area.

The lining of the small intestine is covered with tiny projections with many capillaries. The projections are called villi. Nutrients pass into the capillaries of the villi and then to other organs of the body.
Capillaries in Villi absorb all other nutrients except fat.
