Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.

corrugated cardboard tube - digestive tract

irregular surfaces on the corrugated tube - villi

pump - heart

Plastic tubing - blood vessels

Explanation:

The corrugated cardboard tube represents the digestive tract.  The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.

Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.

The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.

The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body
