Control of the digestive system is also maintained by ENS, which can be thought of as a digestive brain that can help to regulate motility, secretion and growth. Sensory information from the digestive system can be received, integrated and acted upon by the enteric system alone. When this occurs, the reflex is called a short reflex. [4]
Saliva (containing the enzyme amylase) starts the digestion process. [ 3 ] [ 13 ] The food material is swallowed down the esophagus and then reaches the stomach, where digestion continues. The stomach is 15% of the total volume of the GI tract [ 3 ] and has a pH of 1-2 (which is very acidic).

Using artificial digestion, meat samples are dissolved by a digestive solution and the remains are examined for the presence of ...
