What does diastolic blood pressure (DBP) measure?

Pressure during ventricle contraction
Pressure on arterial system during relaxation
Overall blood pressure
Cardiac output derived pressure

The correct answer is: Pressure on arterial system during relaxation

Diastolic blood pressure (DBP) specifically measures the pressure in the arteries when the heart is at rest between beats, particularly during the relaxation phase of the heartbeat known as diastole. During this phase, the heart chambers fill with blood, and the arterial pressure reflects the volume of blood in the arteries at that moment. This measurement is crucial because it provides insight into the resistance the heart must overcome to pump blood effectively and indicates how well the arteries can accommodate blood flow. The concept emphasizes the importance of resting pressure in the cardiovascular system, which can indicate various health conditions, such as hypertension. Understanding diastolic pressure helps in assessing cardiovascular health and managing blood pressure effectively.
