The digestive process begins in the mouth where food enters to be digested. Salivary glands begin  digestion at the sight or smell of food. Once the food enters the mouth the teeth grind up and chew the  food and mix it with saliva. This creates a food mass called a bolus. The bolus then moves out of the  mouth and goes through the pharynx and into the esophagus. From the esophagus the bolus enters the  stomach. The acids in the partially digest the bolus and turn it into a semi-liquid mass called chyme. The  chyme moves from the stomach into the small intestine. Once the chyme is in the small intestine  additional fluid secretions help aid in the digestion process. These secretions, called bile, come from the

The small intestine is divided into three parts; the duodenum, jejunum, and ileum. Any of the components of the chyme that are not absorbed in the small intestine move into the large intestine through a sphincter. The sphincter keeps the undigested materials from re-entering the small intestine. From there the chyme enters into the colon where some water, vitamins, and minerals are absorbed. Anything that is not absorbed in the colon leaves the body as feces....
