Question
What action of the AV and semilunar heart valves matches with the correct statement regarding pressure differences in the heart chambers.Statement: -Atrial pressure is greater than ventricular pressure -ventricular pressure rises above atrial pressure -pressure in the ventricles is greater than the pressure in the great arteries -Ventricular pressure is lower than the arterial pressure
Action: -AV valves open -AV valves closed -semi lunar valve‘s open -semi lunar valve closed

Action: -AV valves open -AV valves closed -semi lunar valve‘s open -semi lunar valve closed
Action: -AV valves open -AV valves closed -semi lunar valve‘s open -semi lunar valve closed
Explanation / Answer
Atrial pressure is greater than ventricular pressure - AV valves open.
Ventricular pressure rises above atrial pressure - AV valves closed.
Pressure in the ventricles is greater than the pressure in the great arteries - Semilunar valves open.
Ventricular pressure is lower than the arterial pressure - Semilunar valves closed.
The opening of blood flow between the right atrium and right ventricle is protected by tricuspid valve and left atrium and left ventricle are attached by bicuspid valve. The opening between the ventricles and aorta is guarded by semilunar valves. The increased pressure in the ventricles opens the semilunar valve and transfers blood into the pulmonary and aortic arteries.
Increased pressure in auricles, then the AV valves open and if the pressure is increased in ventricles that the auricles, then AV valve closed. Increased pressure in ventricles than the aorta, then semilunar valves open, if this valve is closed, then the pressure will increase in aorta than the ventricles.
