Diastole and systole are terms that address the contracting and relaxing of the heart. Which of the following statements about diastolic and systolic blood pressure are true? Select all that apply. The diastolic blood pressure reading is the second number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure in the arteries when the heart rests between beats. Systole refers to when the heart contracts and blood flows from atria into ventricles.
