Answer:

80 mm Hg

Explanation:

Immediately prior to ventricular systole, pressure in the aorta is about 80 mm Hg. This can be explained by the Frank-Starling Law which states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch which tends to cause a more forceful systolic contraction. This applies in the case that all of the other factors remain the same during that time.
