The digestive system is a kind of alimentary canal, connecting several organs and communicating with several glands throughout the digestion process.
Its main functions are:
food intake, grinding, dissolving and mixing food in the gastrointestinal tract (mouth);
digestion of food (ground in the mouth and crushed in the stomach and intestines);
absorb nutrients (small intestine) and water (thick intestine);
and to eliminate some digestion wastes through feces.
The elimination of unnecessary products for digestion (excretion) is not a major function of the digestive system.
The main responsible for the elimination of nondigestible waste is, in the human body, the excretory system (sweat, urine and excretion of carbon dioxide in the breath), while the feces are, in the majority, constituted by digestion residues and bacteria that reside in the digestive tract. .
Digestion is the breakdown of large food components into smaller size in the body.
The digestive system functions includes the chemical breakdown of food, mechanical breakdown of food, absorption of food molecules and elimination of waste products.
The digestive tract can be compare to a tube with two openings - mouth and anus. The process of digestion starts from the mouth ( ingestion of food) through the oesophagus down to the stomach (where the food is mixed with digestive juices) then to the small intestine (this is where most of the digestion process takes place) then to the large intestine and finally to the anus where undigested wastes are eliminated
