PY - 2020 T2 - Current Diagnosis & Treatment: Surgery, 15e AB - The stomach receives food from the esophagus and has four functions: (1) to act as a reservoir that permits eating boluses of food at intervals of several hours; (2) to mix and deliver food into the duodenum in amounts regulated by its chemical nature and texture; (3) to facilitate the first stages of protein and carbohydrate digestion; and (4) to absorb some small molecules across the gastric mucosa.
