During ventricular systole in a cardiac cycle, the option that shows the change in pressure and the state of atrioventricular and aortic valve is:
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
During ventricular systole, ventricular pressure exceeds atrial pressure to pump blood into aorta, AV valves closes to prevent backflow of blood into atria and aortic valve opens to allow for blood flow.So B is correct.

About Cardiac Cycle and Heartbeat
The cardiac cycle describes atrial systole, ventricular systole and diastole, including pressure changes, blood movement and the opening or closing of heart valves. It also covers the conduction pathway from the sinoatrial node through the atrioventricular node, bundle of His and Purkinje fibres, and relates these events to heartbeat sounds.
