A student uses Visking tubing to construct a model of a kidney dialysis machine.

A diagram of the dialysis model. A beaker filled with distilled water contains a tied bag of Visking tubing. Inside the Visking tubing is a solution containing large starch molecules (represented by large circles), glucose molecules (represented by small triangles), and urea molecules (represented by small dots). Arrows indicate small molecules diffusing out of the Visking tubing into the surrounding water, while the large starch molecules remain inside the tubing.

Explain how this experiment represents a simple model of kidney dialysis treatment.
