Mouth and Oesophagus
Food is taken in by the mouth. It is chewed and mixed with saliva then swallowed to pass down the oesophagus into the stomach.
Stomach
In the stomach the digestive juices begin to liquidise the food before it passes into the first part of the small intestine (Duodenum)
Small Intestine
The small intestine comprises of the duodenum, jejunum and the ileum.
Bile from the liver is released into the duodenum to break down the fat in the food.
Further digestive juices continue to break down the food as the food continues through the small
intestine so that the nutrients from the food can be absorbed through the intestinal wall into the blood stream.
Large Intestine (colon)
The remaining food which is now very liquid passes into the colon. The job of the colon is to reabsorb the water leaving the solid waste matter (faeces).
Rectum
The solid waste matter passes from the colon into the rectum where it exits from the body through the anus.
