4. The Small Intestine
This is a very, very long, coiled tube. It's not called 'small' because it's short, but because it's narrow.
Its job is to:
Absorb all the tiny, useful nutrients from the food mush into your blood. This is where your body gets its energy!
💡 Fun Facts
- If you stretched out an adult's small intestine, it would be about 6 or 7 metres long – that's longer than a giraffe is tall!
- The inside is covered in tiny, finger-like bumps called 'villi' which give it a huge surface area to soak up nutrients.
- Food can spend up to 4 hours on its journey through the small intestine.
