Hello! I'm Oscar, and today I am going to run you through the steps of the digestive system!
First the food enters the mouth. It is broken up by the chewing and enzymes in our saliva.
The food then goes down through the oesophagus. Nerves trigger a controlled muscular reaction called peristalsis, which pushes the food down.
In the stomach, the walls of the stomach pound up the food and the stomach acids that are released break it down even more.
In the small intestines, the food is broken up even more, and the nutrients are taken by the blood stream for use.
In the large intestines, most moisture is removed from the remaining waste.
In the rectum, the waste is stored until it is expelled by the body.
