mouth1_460

The digestive process starts in the mouth.
We chew food with our teeth and mix the food with saliva.

oesophagus2_460

Our tongue pushes the food around our mouth to the oesophagus.
The oesophagus is a tube that connects the mouth and the stomach.

stomach1_460

The food travels down the oesophagus to the stomach.

The stomach is like a mixer.
The stomach uses gastric juices to turn the food into a thick liquid.

smallintestine1_460

The thick liquid travels to the small intestine.
The small intestine breaks down the food mixture even more.

liver_pancreas2_460

The liver and the pancreas send juices to the small intestine.
So that the body can now absorb the nutrients in the food.

largeintestine1_460

The remains of the food go the large intestine.

rectum_anus

The remains finally leave the body through the anus.
