A bite of apple travels through a labelled diagram of the body: teeth and saliva in the mouth, down the esophagus, churned into a thick soup in the stomach, then through the small intestine, where nutrients pass into the blood and travel around the body. The large intestine soaks up water from the leftovers before the solid waste leaves the body, and the video ends by naming each part in order.

What the lesson says
Where does your food go after you eat it?
It takes a long trip through your digestive system.
First, in your mouth, your teeth chew the food into small pieces.
Saliva, or spit, makes the food wet and soft, so it is easy to swallow.
When you swallow, muscles squeeze the food down a tube called the esophagus.
The food drops into your stomach, a stretchy bag made of muscle.
Your stomach churns the food and mixes it with strong juices until it is a thick soup.
Next, the soup moves into the small intestine, a long, narrow tube coiled up in your belly.
Here, the useful parts of food, called nutrients, pass into your blood.
Your blood carries the nutrients all around your body.
What is left moves into the large intestine, which is wider but shorter.
The large intestine soaks up water from the leftovers.
The solid waste that is left leaves your body when you use the toilet.
So food travels from your mouth, down your esophagus, into your stomach, then through your small and large intestines.
