Stages of food processing in the body
Processing of food in the alimentary canal is divided into separate stages.
|Ingestion||Physical intake of food|
|Digestion||Breakdown of large, insoluble matter into small soluble molecules|
|Absorption||Movement of digested molecules from the gut into the blood stream|
|Assimilation||Processing of absorbed nutrients for use by the body|
|Egestion||Removal of undigested material and unabsorbed material from the gut|
The alimentary canal forms a factory line for the different digestive processes.
