Blood pressure varies between systolic and what other type of pressure?

Blood pressure is measured in two phases: systolic pressure and diastolic pressure. Systolic pressure is the force exerted on the walls of the arteries when the heart beats and pumps blood. In contrast, diastolic pressure measures the pressure in the arteries when the heart is at rest between beats. This resting phase is critical for understanding the overall health of the cardiovascular system, as it reflects how well the arteries can accommodate blood flow when the heart is not actively pumping.

Recognizing the significance of diastolic pressure is essential for determining normal ranges of blood pressure and diagnosing conditions like hypertension. Monitoring both pressures provides a complete picture of cardiovascular health. To summarize, the correct answer highlights the relationship between systolic and diastolic pressures, which are fundamental components of blood pressure readings.
