What is the lowest point of blood pressure during the heart's relaxation phase called?

• A. Systolic blood pressure
• B. Diastolic blood pressure
• C. Resting blood pressure
• D. Baseline blood pressure

Answer: (B)

The lowest point of blood pressure during the heart's relaxation phase is referred to as diastolic blood pressure. During this phase, the heart muscle relaxes, allowing the chambers of the heart to fill with blood. At this moment, the pressure in the arteries is at its minimum before the next heartbeat. This measurement is crucial because it reflects the baseline pressure in the arteries when the heart is not actively pumping blood. Monitoring diastolic blood pressure is important for assessing overall cardiovascular health, as persistently high levels can indicate potential health risks like heart disease or hypertension. In contrast, systolic blood pressure, which is measured during heart contractions, represents the maximum pressure in the arteries when the heart beats. The other options do not accurately define this concept; resting blood pressure and baseline blood pressure are not standard medical terminologies used to describe the specific phases of blood pressure during the cardiac cycle.
