Mouth, esophagus, stomach
Salivary glands.
The digestive enzyme-amylase is secreted in two regions of the digestive tract.i.e.(1) salivary amylase by salivary glands in the buccal cavity.(2) pancreatic amylase by pancreas in the duodenum.
The action of chewing produces extra saliva - which contains digestive enzymes.
Interferons are normally injected. They are not taken by mouth as the strong digestive enzymes of the stomach will degrade them
The first digestive juices are those produced in saliva that is excreted into the mouth.
They are called digestive enzymes. There are many that are used in the process, beginning in the mouth with enzymes that begin the break down of starches.
The esophagus is responsible for transporting food and liquids from the mouth to the stomach through a series of muscular contractions called peristalsis. This process ensures that food is moved efficiently and safely from the mouth to the stomach for digestion.
Most of the digestive process occurs in the duodenum and jejunum of the small intestine. This is where food mixes with digestive enzymes from the pancreas and bile to break down nutrients into forms that can be absorbed by the body.
Digestion in the mouth accounts for about 5-10% of the total digestive process. The primary function in the mouth is mechanical breakdown through chewing, along with the enzymatic action of saliva, particularly the enzyme amylase, which begins the digestion of carbohydrates. Most digestion occurs in the stomach and small intestine, where further breakdown and absorption of nutrients take place.
because of the digestive system
The mouth is part of the digestive system. It is where the process of digestion begins, as food is broken down into smaller pieces by chewing and mixed with saliva to begin the process of enzymatic breakdown.
