Simbiotic digestion takes the important place in the digestive conveyor of the of human gut. It is carried out numerous lumen and mucosal microflora providing variety nutrients. Simbiotic digestion as well as own digestion, begins in a mouth. Most the great value has this type of digestion in small gut and, especially, large gutdigestion as in ileum to a bowel practically there is no own digestion. Simbiotic digestion at the human joins in mechanisms of own digestion, supplementing and expanding processes of digestion and absorb food substances. Results of research expand representations about digestive process in a human body and allow to allocate 4 stages in its mechanisms: lumen simbiotic digestion – mucosal simbiotic digestion membrane digestion absorbtion. The scheme of the digestive conveyor of the human gut taking into account own and simbiotic digestion is offered and new ways to studying of this problem are planned.
