The students constructed a model of the digestive system using playdough, clothes pins, cardboard, and other materials. They made the esophagus, stomach, liver, large intestine, and small intestine. The digestive system breaks down food through processes in the mouth, esophagus, stomach, small intestine, and large intestine to extract nutrients for the body and remove waste.

First: we do the shape of the esophagus with
the playdough.
 Second: we do the shape of the stomach
and the liver with the playdough.
 Third: we do the large intestine with the
clothes pins
 Finally: we do the small intestine with the
half part of the clothes pins.

4. HOW DOES THE DIGESTIVE SYSTEM WORKS?

Whitout this system , the body would not be able to
obtain energy and nutriens

Saliva begins to form in your mouth .Once the food is
swallowed it goes down the esophagus
.

Then, the muscles of the esophaghus push the food
down into the stomach .Atached to the end of the
esophagus is the stomach where the food mix up into
a pulp.

5. HOW DOES THE DIGESTIVE SYSTEM WORKS?

From the stomach the pulp goes into the
small intestine –starts at the end of the
stomach. Here the nutriens from the food
pass into the blood .

After that most of the nutriens are removed
from the blood mixture(There is lest over ).
The large intestine pushes the waste into the
rectum. Here, feces are formed.
