The mouth is the entry point for food, but the digestive system often gets ready before the first piece of food even enters our mouth.
The pharynx and esophagus
The pharynx (throat) is the transition area from the mouth to the esophagus. From the pharynx there are two paths that the food bolus can take; 1) the wrong path,
The stomach and small intestine
From glands that line the stomach, acid and enzymes are secreted that continue the breakdown process of the food. The stomach muscles further mix the food
The colon, rectum, and anus
The role of the lower GI tract is to solidify the waste product (by absorbing water), store the waste product until it can be evacuated (going to the bathroom) and help with the evacuation process.
