Final answer:
Pulse pressure is correctly defined as the difference between systolic and diastolic blood pressures, and this is a true statement. It is an important measurement for assessing cardiovascular health.
Step-by-step explanation:
Pulse pressure is indeed the difference between systolic and diastolic blood pressures. This is a true statement. If a person has a systolic pressure of 120 mm Hg and a diastolic pressure of 80 mm Hg, their pulse pressure would be 40 mmHg. It's important to monitor both systolic and diastolic pressures as they have significant health implications. For example, high systolic pressure raises the risk of heart attack and stroke, whereas high diastolic pressure can indicate problems with blood vessel dilation and fluid balance, potentially placing a strain on the heart.
