Ingestion is the first function of the digestive system. Food must be taken in by the mouth before anything else can take place.
Mechanical Digestion is the second function of the digestion system. Food is masticated and mixed with salivary secretions to begin the breakdown process in preparation for the mixing actions further on in the process.
Movement The act of swallowing and the movement of the chewed food down the oesophagus to the stomach. In the stomach more digestive fluids are added to make a "soup" which further breaks down the food molecules into usable size. Think of the stomach as a small washing machine that agitates and sloshes that soup all about breaking it up and liquefying it.
Absorption Molecules resultant from chemical digestion are absorbed by the lining of the small intestine. Further absorption of water and molecules takes place in the large intestines.
Elimination food that cannot be digested must be eliminated from the digestive system. This is called defecation/elimination.
