Notes+p7+Digestive

Digestion is the turning of food you eat into energy. It also creates waste that the body eliminates. The first place that food goes on its journey through the digestive system is the mouth. In the mouth, we chop the food into small pieces that make digestion easier. The food makes our saliva produce much more quickly. That makes digesting much easier because the saliva breaks down the food. The next stop is the pharynx and then the esophagus. Another name for the pharynx is the throat. All that it really does is carry the food from the mouth to the esophagus. When Food goes through the esophagus and then goes into the stomach. Stool, or waste left over from the digestive process, passes through the colon by means of peristalsis, first in a liquid state and ultimately in solid form. As stool passes through the colon, any remaining water is absorbed. Stool is stored in the sigmoid (S-shaped) colon until a "mass movement" empties it into the rectum, usually once or twice a day.

In biology the small intestine is the part of the gut between the stomach and the large intestine, and comprises the duodenum, jejunum, and ileum. It is where the vast majority of digestion takes place. Nutrients diffuse through the villi, projections sticking out of the walls of the small intestine and goes into the blood. The stomach is a hollow muscular organ of the gut involved in the second phase of digestion which follows mastication.
