The Digestive Process MOUTH STOMACH SMALL INTESTINE LARGE INTESTINE ANUS The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules). After being chewed and swallowed, the food enters the esophagus . The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we're upside-down. The stomach is a large, sack-like organ that churns the food and bathes it in a very strong acid (gastric acid). Food in the stomach that is partly digested and mixed with stomach acids is called chyme. 1) Stores swallowed food and liquid 2) Mix the food and liquid with digestive juice 3) Empty contents into small intestine 4) protein synthesis After being in the stomach, food enters the duodenum, the first part of the small
