The chewed food enters into the food pipe or oesophagus and is then slowly pushed into a bag like structure called stomach. The food is churned in the stomach to further break it down. The stomach also secretes mucous, digestive juices and hydrochloric acid. The hydrochloric acid kills the bacteria in the food and makes the food acidic.
The food then goes into a highly coiled tube called small intestine. The small intestine receives secretions from the liver and pancreas. The liver secretes bile juice while the pancreas secretes pancreatic juice. The walls of the small intestine also secrete juices, which help in further digestion of food.
