Gastrointestinal physiology

Gastrointestinal physiology is concerned with the physical function of the gastrointestinal tract (GI). The function of the GI tract is to process consumed food by mechanical and chemical means, extract nutrients and secrete waste products. The GI tract is composed of the alimentary canal, that runs from the mouth to the anus, as well as the associated glands, chemicals, hormones, and enzymes that assist in digestion. The key processes that occur in the GI tract are: motility, secretion, regulation, digestion and circulation. The proper function and coordination of these processes are required for maintaining good health by providing for the effective digestion and uptake of nutrients.
