Food enters the mouth


Teeth mechanically digest food by tearing and crushing; enzyme in saliva chemically digests starch molecules into sugar molecules


Tongue pushes food to back of mouth


Pharynx swallows food


Esophagus coats food with mucus; peristasis, waves of muscular contractions, begin here, pushing food along


Food travels through ring-like muscle called the cardiac sphincter


Food enters stomach where it is mechanically digested by churning and where proteins are chemically digested into amino acids by gastric juices, which contain an enzyme and acid.


Food in the form of a paste passes through the pyloric sphicter one teaspoon at a time.


Food enters the small intestine. Bile, made by the liver and stored in the gall bladder, is sent here by way of a duct. This bile mechanically digests fats into smaller portions of fat. Enzymes made by the pancreas are sent here where they chemically digest remaining carbohydrates and proteins. They also chemically digest fats into smaller molecules called fatty acids and glycerols.


The small intestine is lined with small finger-like projections called villi. Inside the villi are blood vessels. Once all chemical digestion is completed, the sugars, amino acids, fatty acids and glycerols travel through the lining of the cilli and into the blood. The blood then distributes them to the cells of the body.


Any food that was eaten but was not digested moves into the large intestine, otherwise known as the colon. As it travels through the colon much of the water is reabsorbed.


The waste, known as feces, enters the rectum where it is stored until it is elimated.


Feces are elimiated through the anus.
