Which of the following describes diastolic pressure?

Diastolic pressure refers to the lowest pressure in the arteries during the relaxation phase of the heart cycle, known as diastole. This phase occurs when the heart's chambers are filling with blood, specifically when the ventricles are relaxed and the heart is not actively contracting. This is significant because it indicates the minimum level of pressure present in the arteries, ensuring that blood continues to flow effectively to various tissues even when the heart is at rest.

Understanding diastolic pressure is essential for evaluating cardiovascular health, as it provides insight into the resistance of the blood vessels and overall blood pressure regulation. It is typically measured alongside systolic pressure, which represents the pressure during heartbeats, thus providing a complete picture of cardiac function and vascular health. By knowing that diastolic pressure measures the lowest pressure during relaxation, one can better appreciate its role in maintaining an adequate blood supply throughout the body.
