The organs produce digestive chemicals (enzymes and acids) that break down the nutrients into simpler forms so that absorption through the intestinal wall and into the blood stream can occur. Mechanical and Chemical Digestion.

Mechanical and Chemical Digestion. There are two kinds of digestion: mechanical and chemical.
Chemical 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.Absorption is the uptake of fluids or other substances by the tissues of the body.ost 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.
