2. The left beaker simulates blood coming from the lungs. The right beaker simulates blood traveling to the systemic circuit.

3. Describe how the heart alters stroke volume.

The heart alters stroke volume by altering contractility, the force of contraction. Increasing the force of contraction will increase stroke volume.
