3. Which of the following occurs during ventricular systole?
A. Increased aortic pressure
B. Increased ventricular volume
C. Dup heart sound
D. P wave
answer is A and I don't understand why.
All I learned at this stage is
ventricular pressure goes up
atria pressure goes down
AV valve closes.
And isn't ventricle supposed to eject blood from heart at this stage?
To do so, it should open semiluar valve but if aortic pressure is higher than ventricle pressure, I think all the blood will back flow into the ventricle.
