The fluid that starts digestion is saliva. It is not the most important part of the digestive process, but it is the first part. * The part that everyone knows about comes next. When food enters the stomach it contacts pepsin, the most important digestive enzyme. The arrival of food stimulates the stomach to secrete deci-normal hydrochloric acid. This activates the pepsin. * If you have trouble believing this, try an experiment. Next time you get something stuck between your teeth, don't spend five minutes digging it out. Leave it strictly alone. In less than an hour, the saliva in your mouth will have digested enough of the surface of the food particle to make it a loose fit between your teeth, so it falls out.
The large intestine in the human body has to do with the digestion process because it has a job to absorb all the salt and liquid of the food. Hope this helps!
The main parts of the digestive system are the mouth, esophagus, stomach, small intestine, large intestine, liver, gull bladder, and pancreas. Food does not actually pass through the liver, gull bladder and pancreas, but they do produce a green liquid called bile that helps digestion.

Yes, bacteria in the intestine aid with digestion.
helps in digestion and absorbs the nutrients into your body.
Minor fiber digestion by bacteria goes on in the large intestine, and water is absorbed, but no major lipid/protein/carbohydrate digestion occurs. All of that goes on higher up in the system.
Digestion occurs in the stomach and small intestine. The liver helps via metabolism of nutrients (but not by digestion).
pancreas The liver, gallbladder and pancreas all send chemicals to your small intestine.

Yes, the pancreas produces lipase. Lipase is an enzyme that helps break down fats in the digestive system. It is secreted by the pancreas and helps in the digestion and absorption of fats in the small intestine.
The gallbladder stores and releases bile, a fluid that helps break down fats in the small intestine during digestion.
The digestion system breaks down food. Digestion begins in the mouth and ends in the small intestine.
