During the circulation of blood, the blood pressure drops slowly as it moves away from the heart through arteries, and toward the heart through veins.
Diastolic blood pressure varies depending on the activity, surrounding temperature, diet-taken, state-of-mind (emotional), physical posture and medication used.
Diastolic blood pressure
Diastolic blood pressure is minimum pressure in the arteries, which generates near the beginning of the cardiac cycle when the ventricles are filling with blood.
As said before blood pressure reading is representing by two numbers one over the other, for example, 110 over 70 in millimeters of mercury (mmHg). The bottom number is diastolic blood pressure reading, and it is the minimum pressure in the arteries when the heart is at rest.
Importance of Diastolic Blood Pressure
Diastolic blood-pressure readings are specifically important in the monitoring of the blood pressure in younger individuals.
