- Your front teeth cut up the Baked Beans and your back teeth mash and grind them.
- The Baked Bean mash is rolled into a ball by your tongue then pushed down your oesophagus.
- The digestive juices in your stomach break the food down.
- The nutrients are digested and absorbed in your small intestine.
- The leftover food (bean skin) has the water removed from it when it passes through your large intestine.
- And it is then stored in your rectum until you push it out your anus as poos.
- What happens to the Baked Beans happens to everything you eat.

- Your body makes about a litre and half of saliva every day.
- The gases produced in your digestive system, when it breaks down the food, often escapes as a burp.
- You have about 7 meters of intestines curled up inside your body.
- It can take 10 hours for food to move from one end of your intestine to the other.
- By the time you’re 70 you’ll have eaten 30,000 kilograms of food (6 whole elephants).
- This digestion process happens to animals too - food is broken down in the digestive system of the animal (some systems work a bit differently but they do the same sort of job) and wastes (poos) are passed out through the animal’s bottom!

- Next time you eat baked beans or spaghetti concentrate on how your mouth works.
- How does your tongue move the beans around?
- Can you feel any burps rising up from your stomach?
- Bite into an apple and think about how your teeth work.

- Observe a cat or dog eating. Do they use their sharp teeth the same way you do?
- Think about the sorts of things they eat? How is it similar or different to what you eat? Would their digestive system work in the same way as yours?
- Find out about the digestive system of a cow or a goat!

- How come skeletons don’t eat baked beans?
