Solution
The correct option is C Y
Normal blood pressure is higher 120/80. In this measurement 120 mm Hg (millimetres of mercury pressure) is the ventricular systolic, or pumping, pressure and 80 mm Hg is the diastolic, or resting, pressure. Hence, letter Y in graph which corresponds to 120mm of Hg is ventricular systole.
