How is the small intestine designed to absorb digested food?

The inner lining of the small intestine has numerous finger-like projections called villi.
These villi significantly increase the surface area for the absorption of digested food.
Each villus is richly supplied with blood vessels and lacteals (lymph vessels).
The blood vessels absorb the digested food (nutrients like glucose,amino acids) and transport it into the bloodstream.
From the bloodstream,the absorbed food is delivered to each and every cell of the body for energy production,growth,and repair.
