The digestive system - Part 2
After all of your food has been churned up in
your stomach, the goodness is taken out of the
food and goes to other parts of your body such
as the liver, pancreas, and gallbladder.
Small intestine
The small intestine is 6.5 metres long! Your food
is broken down even more in this stretchy tube.
Vitamins, minerals, carbohydrates, proteins, and
fats are taken to the rest of your body for growth,
energy, and cell repair.
Large intestine
The large intestine pushes all the waste from
your food to your rectum. Any food that the
body doesn't need leaves the body as waste
when you go to the toilet.

The liver gets rid of toxins that your body doesn't need. Toxins are substances that can be
