The correct answer focuses on understanding the function of diastolic pressure within the context of blood pressure measurement. Diastolic pressure measures the amount of force exerted by the blood against the walls of the arteries when the heart is at rest between beats. This resting phase allows the heart to fill with blood before it contracts again, and thus, the diastolic pressure reflects the pressure level in the arteries during this crucial period. This distinction is fundamental in the assessment of cardiovascular health, as it provides insight into how well the heart and blood vessels are functioning while the heart is not actively pumping. The definition of diastolic pressure is critical for professionals in the medical field, as it helps them interpret blood pressure readings and assess patients’ cardiovascular status.
