Most of the absorption part of the digestive process occurs in the jejunum and the ileum of the small intestine, though alcohol is readily absorbed through the stomach.hemical processes that contribute to digestion also begin in the mouth with action of saliva on food. However, most of the chemical digestive processes occur in the stomach and small intestine-where the partly-digested materials are subjected to gastric juices, pancreatic juice, succus entericus and so on.
It is the part of the digestive tract where approx 90% of the digestion and absorption of food occurs, the other 10% taking place in the stomach and large intestine. The main function of the small intestine is absorption of nutrients and minerals.That is, absorption of the nutrients and minerals in the food ingested, usually via the mouth, at an earlier stage in the digestive process. Sodium ions (Na +) move from the lumen of the small intestine into epithelial cells by diffusion and active transport. 2  They are then actively transported into blood capillaries on the other side of the epithelial cells. 3  Chloride (Cl -) can passively follow Na + ions into epithelial cells, or be actively transported.
