Definition of Digestive system The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). In this system, the process of digestion has many stages, the first of which starts in the mouth.

Definition of digestive enzymes Digestive enzymes are a group of enzyme that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body.

Secretion of Digestive enzymes in the body Digestive enzymes are found in the digestive tracts of animals (including humans) . Digestive enzymes of diverse specificities are found in the saliva secreted by the salivary glands, in the secretions of cells lining the stomach. the pancreatic juice secreted by pancreatic exocrine cells, and in the secretions of cells lining the small and large intestines.

Chemical Reactions in Food Digestion. There are many chemical reactions in food digestion process These reactions depend on the type of food to be digested whether it is carbohydrate fat or protein This chemical reactions include : Carbohydrate Digestion Protein Digestion Fat Digestion
Carbohydrate Digestion Chemical digestion of carbohydrates begins in the mouth. Your* saliva contains an enzyme called amylase that helps break down the complex unit of carbohydrates into simpler carbohydrates. Digestion of carbohydrates continues in the small intestines, where carbohydrases, which are enzymes that break down carbohydrates, continue to process the carbohydrates into smaller units called glucose, which are absorbed into your bloodstream.
Protein Digestion Protein digestion starts in the stomach. The acid in the stomach, along with the enzyme protease, starts to denature, or unravel, the protein strands for digestion. Like carbohydrates, chemical digestion of proteins continues in the small intestines, where the proteases continue to break down the protein into amino acids, which are then absorbed through the walls of your intestines into your bloodstream.
Fat Digestion All fat digestion takes place in the small intestines. Fat molecules are first mixed with bile, which is a substance made by your liver. Bile dissolves the fat to make it more water soluble, so the fat enzymes, called lipases, have an easier time breaking up the molecule. The lipases break the fat molecule into two parts, glycerol and fatty acid, which is then absorbed like glucose and amino acids.
