anatomical location

the first section of the GI tract is the mouth where the food is consumed and ingested with aid of saliva. following the mouth is the oesophagus where the food moved down towards the stomach after ingestion.

the stomach is a muscular sac holding food to be digested by acids and enzymes and can be located on the left side of the body at the upper abdomen. nutrient absorption and digestion after the stomach happens within the small intestines which has a length of about 20 feet. The jejunum, ileum, and duodenum are the three sections that make up the small intestine. any undigested material is eliminated through water absorption.
