Content: There are tinier projects on each villus called microvilli. These folds make a huge area for absorbing food. The small intestine absorbs and passes along 90% of all the protein, fat and carbohydrates that you eat, along with a small amount of vitamins and minerals. Amino acids, sugars, vitamin C, the B vitamins, iron, calcium and magnesium are carried through the blood stream to your liver where they are processed and sent to the rest of the body. Fatty acid, cholesterol, and vitamins A, D, E, and K go into the lymph system and then into the blood. These also go to the liver, get processed and sent out to other cells in the body. Duodenum
It is a 10-inch long C-shaped tube found around the head of the pancreas which forms the first part of the small intestine right after the stomach. The food, now chyme, enters from the stomach into the duodenum where it is mixed together with the bile and other digestive juices produced by the accessory digestive organs and drained into the duodenum. Absorption of food also begins here with the absorption of vitamins, minerals and other nutrients. In particular, before the food passes into the next part of the small intestine iron, calcium and magnesium are absorbed here.
