Anus carbohydrate digestion from mouth
The esophagus produces no digestive enzymes but does produce mucous for lubrication. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. The combined action of these processes modifies the food from large particles to a soft mass that can be swallowed and can travel the length of the esophagus. These small globules are more widely distributed in the chyme rather than forming large aggregates. Obtaining nutrition and energy from food is a multi-step process. The internal sphincter is always tight, except when stool enters the rectum.
Anus carbohydrate digestion from mouth. Water, bile, enzymes, and mucous contribute to the change in consistency. However, the bulk of lipid digestion occurs in the small intestine due to pancreatic lipase. It takes the raw materials absorbed by the intestine and makes all the various chemicals the body needs to function. Once the nutrients have been absorbed and the leftover-food residue liquid has passed through the small intestine, it then moves on to the large intestine, or colon. Emesis, or vomiting, is elimination of food by forceful expulsion through the mouth.

The long-chain fatty acids and monoglycerides recombine in the absorptive cells to form triglycerides, which aggregate into globules and become coated with proteins. For true animals, the first step is ingestion, the act of taking in food.
