What does diastolic pressure indicate?

  1. The pressure in the arteries when the heart is contracting

  2. The pressure remaining in the arteries when the heart relaxes

  3. The pressure during normal breathing cycles

  4. The pressure in the arteries during physical exertion

The correct answer is: The pressure remaining in the arteries when the heart relaxes

Diastolic pressure reflects the pressure in the arteries when the heart is in a state of relaxation, specifically between beats. When the heart contracts, it pumps blood into the arteries, leading to systolic pressure, which represents the maximum pressure. However, during diastole, when the heart is at rest and filling with blood, diastolic pressure measures the minimum level of pressure in the arteries. This is crucial for understanding cardiovascular health, as it indicates how well the arteries are able to maintain blood flow during the resting phase of the cardiac cycle. High diastolic pressure can indicate issues such as increased vascular resistance or other cardiovascular concerns. In contrast, the other options describe different aspects of cardiovascular function that do not accurately represent diastolic pressure.
