Question 2
Sammi decides to design a model to show how the digestive and circulatory systems interact. She lines a large plastic tube
with a corrugated cardboard tube. Then, she connects smaller plastic tubes to the large plastic tube. These small tubes
connect to a pump. She drills small holes in the large tube so that all of the plastic tubes connect.
She plans to run a green fluid representing food through the cardboard tube.
