In class we have been learning about the digestive system.

The first stage of the digestive system is the mouth.

The mouth breaks down the food using our teeth and saliva.

There is a muscle called the gullet that helps the food get pushed into the esophagus. The esophagus is a really long tube that leads to the stomach.

In the stomach there is an acid that helps the food melt to liquid and break the food to even smaller pieces. It takes 4 hours to melt.

Then we have the small intestine that absorbs the vitamins and minerals.

The large intestine is a big fat tube that leads to the rectum. The large intestine absorbs the salt and water.

The rectum is the last step. The rectum gets rid of wastes and all the stuff you don't need.
