Describe the function of the two general types of heart valves and papillary muscles (be clear what each type of valve does and how the papillary muscles facilitate the valves function). If there is damage to the papillary muscle on the left ventricle, which valve is affected? 3. Explain how the valve in question might increase, decrease, or maintain stroke volume? 4.
