Primary project

1. 1. We chew the food with
our teeth in the mouth.
2. The food goes to
the esophagus
and then, it goes to
the stomach.
3. The stomach
produces gastric
juices.
4. The stomach mixes:
- The food.
- The gastric juices.
- The juices from the liver.
- The juices from the
pancreas.
It makes a thick liquid.
5. The thick liquid goes
to the small intestine.
The small intestine
absorbs the nutrients
from the food.
6. The large intestine:
- Stores the matter that
we don’t need (faeces).
- Absorbs water.
7. The faeces are
released through the
anus.

2. The digestive system transforms the food into
nutrients that our body needs:
- Vitamins.
- Carbohydrates.
- Fats.
- Proteins.
- Minerals.
The digestive system gets rid of the matter
that our body doesn’t need.
