Jorin is building a model that shows how two different human body systems interact. he cuts a hole in a plastic tube, places a water filter in the hole, and connects a smaller tube directly to the filter. his model is shown below. picture of a water filter jorin tests the model by running dirty water through the larger tube. soon, the smaller tube begins to fill with clear water. which two body systems is jorin most likely using his model to simulate?
