The small intestine is all about maximizing surface area. The immense amount of folding enables it to be very long meaning more surface area. The villi further increases surface area. They are projections that provide even more membrane surface area that food, while passing through the small intestine, will come in contact with. This contact with the membrane of the small intestine is how absorption occurs. Nutrients that are used in the body will diffuse across the intestinal membrane into the blood stream because the concentration will be high inside the intestine and low in the blood plasma. This difference in concentration is what "drives" diffusion across the membrane.

Where and when does lactose metabolism occur in humans?
Lactose metabolism occurs in the small intestine of humans. It begins when lactase, an enzyme produced by the small intestine, breaks down lactose into glucose and galactose. This process allows the body to absorb these simple sugars for energy.
Where does most nutrients reabsorption occur?
Most nutrient reabsorption occurs in the small intestine, particularly in the jejunum and ileum. These sections of the small intestine have specialized cells that absorb nutrients such as sugars, amino acids, and vitamins from digested food into the bloodstream for distribution to the rest of the body.
