Related to digestive system: Digestive system diseases
The digestive tract and digestive glands regarded as an integrated system responsible for the ingestion, digestion, and absorption of food.
the system by which ingested food is acted upon by physical and chemical means to provide the body with absorbable nutrients and to excrete waste products: in mammals the system includes the alimentary canal extending from the mouth to the anus and the hormones and enzymes assisting in digestion.
In anthroposophical medicine this is one of three systems (the other two being the nerve/sense system and the rhythmic system) which together link the physical, etheric body, astral body and ego.
