Final answer:
Diastolic blood pressure tends to increase with age.
Step-by-step explanation:
Diastolic blood pressure tends to increase with age. According to the provided information, the common arterial blood pressure measurements typically produce values of 120 mm Hg and 80 mm Hg for systolic and diastolic pressures, respectively. High diastolic pressure is an indication that blood vessels are not dilating properly to pass blood through, which can strain the heart in its attempt to pump blood. Therefore, as age increases, diastolic blood pressure tends to increase.
