The mouth and oesophagus
The food is ingested and chewed whilst being mixed with saliva so that the food breaks down even more. It then travels down the oesophagus after you swallow.
The stomach
The broken down food then enters the stomach which has substances called enzymes to help digest the food. It will do then break the food down further into a liquid.
The small intestine
This is where most of the digesting happens, also absorbation of the food particles then takes place.
The large intestine
By the time the food reaches the large intestine most of the nutrients have been absorbed, water, salt and ingestible fibres are left and then the water is absorbed as well.
Rectum and anus
The remaining substances, called faeces, are then passed through the rectum and then out through the anus. This is called egestion.
Pancreas
Located in the abdomen, convert food to fuel for body's cells, helps digestions and regulates blood sugars.
Liver
Production of bile which helps carry away waste and breaks down fats in the small intestine during digestion. Production of certain proteins for blood plasma.
