Whenever we eat food then we chew it,grind it,tear it using our teeth and saliva present in our mouth contains an enzyme known
as salivary amylase which break down starch into simple sugars then food travels.

Along the elemantary canal then it reach stomach  where gastric gland release HCL which help an protein enzyme pepsin help in changing protein into protease and mucus protect the inner lining of stomach from acidic medium created by HCL.

 Then the food reach small 
intestine it can be completely 
digested here through bile juice 
and trypsin then after breaking 
down of this the food materials get
 excreated by anus.
