Which of the following describes the typical left ventricular pressures during systole and diastole?

During systole the left ventricle must generate a high pressure to eject blood into the aorta, while in diastole the pressure falls to a low level as the ventricle relaxes and fills. In a healthy adult, left ventricular systolic pressure is about 120–140 mmHg, and the diastolic pressure is about 3–12 mmHg. The option that lists roughly 120–140 mmHg for systole and 3–12 mmHg for diastole best reflects these normal values. The other ranges either overestimate diastolic pressure or underestimate systolic pressure, so they don’t fit the typical LV pressure profile.
