What are the steps in the digestive process?
There are five major steps in the process of digestion.
Ingestion: the eating of any food
Peristalsis: the involuntary muscle contractions that move the ingested food through the digestive tract
Digestion: the conversion of the food molecules into nutrients that can then be used by the body
Absorption: the passage of the nutrients into the bloodstream and/or lymphatic system to be used by the body’s cells
Defecation: the elimination of the undigested and unabsorbed ingested materials
