Digestive system. Computer artwork of the human digestive system. Food from the mouth travels sequentially through the stomach (upper right),small intestine (coils,centre) and large intestine (clockwise from lower left to lower centre). It is propelled through the system by muscular contractions (peristalsis),which also aid the digestive process. Enzymatic breakdown of food in the stomach and small intestine releases nutrients. These are absorbed into the blood and the lymphatic system through the intestinal linings. Undigested matter passes into the rectum and is expelled from the body as faeces | |
