24 CVCK Student Lab ManualBased on your observation of the simulation and the data you entered into the tableabove, indicate which of the following statements are true:_ _ _ _ When the pressure at point A is higher than the pressure at point B,the valve opens._ _ _ _ When the pressure at point B is higher than the pressure at point A,the valve opens._ _ _ _When the valve is open, the pressure at B is lower than the pressure atA, and when this changes (pressure at B becomes lower), the valvecloses._ _ _ _When the valve is closed, the pressure at A is higher than the pressureat B, and when this changes (pressure at B becomes higher than thepressure at A), the valve opens._ _ _ _There are times when the valve is closed, but there is blood flow._ _ _ _Whenever there is blood flow, the valve is open._ _ _ _Blood flow is controlled entirely by pressure, other factors such as theexistence of valves, and the concentrations of oxygen do not determinewhether or not there is blood flow._ _ _ _Valves determine the direction in which blood will flow._ _ _ _Valves allow blood flow in two directions.
