the pharynx lubricates food and passes it to the oesophagus
the oesophagus Passes the food to the stomach
ma boy the stomach does most the work, with its hydrochloric acid, it mixes and churns foods, it Stimulates protein-digesting enzymes Absorbs some fat-soluble substances Begins chemical breakdown of proteins and Releases food into the duodenum as chyme
the gallbladder stores, concentrates, and releases bile
the small intestine Absorbs breakdown products of carbohydrates, proteins, lipids, and nucleic acids, along with vitamins, minerals, and water
