The digestion consists of reducing all foods in elementary substances simpler, able to happen to the blood to be used by the organism:

of the digestive apparatus is to assure the digestion. The assimilation of different foods is obtained by its degradation in simple elements: fatty acid lipids, glúcidos in simple sugars (bears) prótidos in amino acids.
The set of these transformations needs combined mechanical and chemical actions. The mechanical actions consist of movements of mixed (

The enterocitos also synthesize enzymes of degradation like glucidasas, proteases and perhaps lipasas.
Let us remember that they produce secretina that triggers the pancreática secretion.
