Small Intestine
We previously learned that food you ingest begins to break down in the mouth. Once food is mixed with saliva, it is passed down through the pharynx and esophagus to the stomach where it is broken down further. Even though the food has now been in your digestive system for a few hours and has gone through a fair amount of processing, only a small portion of total digestion has taken place and even less absorption of nutrients.
