22 CVCK Student Lab ManualExercise 6: The Behavior of ValvesThis exercise focuses on the behavior of valves under different pressure conditions.Construct the system shown in Figure 10, and attach pressure gauges to the pointsmarked A and B, and a flow gauge to the point marked C. These gauges will allowyou to determine whether or not blood is flowing through the valve at any givenpoint in time, and to measure the pressure on the two sides of the valve at thatpoint.CABFigure 10: Measurements to determine when (under what pressureconditions) valves open and close.First run the system for two heart beats to get an idea of how the graphs will appear.
