Digestive system. Animation showing the anatomy of the digestive system (left) and the movement of food through the upper digestive system (right). At left, the liver is orange, the stomach is blue, the small intestine is yellow and the large intestine is black and grey. As food moves down the oesophagus (gullet), circular muscles in its wall contract behind the food, pushing it along. This rhythmic movement is known as peristalsis and occurs throughout the digestive tract. From the oesophagus the food moves to the stomach, where it is stored and partially broken down before moving to the small intestine to be digested. | |
