Digestive System

The food we eat is digested by the body with the help of the mouth, stomach and intestines. Digestion is the process of breaking down the food to simpler forms so that it can be absorbed by the body.

When we eat food it is chewed by our teeth and gets mixed with the saliva in our mouth. Thus the food gets moist and slippery and is pushed into the food pipe or oesophagus. The oesophagus contracts and pushes the food into the stomach.

The stomach is a J- shaped body, made of muscles. The juices of the stomach act on the food and it is passed into the small intestine. The small intestine is a coiled tube which is about 20 feet in length. Here the juices from the pancreas and gall bladder help to digest the food. The digested food is absorbed by the walls of the small intestine. The remaining undigested food is passed into the large intestine. Here water from the food is absorbed and the undigested food is thrown out of the body through the anus.

The food absorbed by the small intestine enters the blood. This blood flows into the liver. The liver stores the nutrients from the food and also changes the food from one form to another. These nutrients are then sent to different parts of the body.
