Detailed explanation-1: -Systolic blood pressure, the top number, measures the force the heart exerts on the walls of the arteries each time it beats. Diastolic blood pressure, the bottom number, measures the force the heart exerts on the walls of the arteries in between beats.

Detailed explanation-2: -The top number is called “systolic blood pressure” (120) and measures blood pressure when the heart pumps. The bottom number is called “diastolic blood pressure” (80) and measures blood pressure when the heart rests between beats.

Detailed explanation-3: -Blood pressure consists of two numbers. Systolic pressure, the force exerted on blood vessels when the heart beats, is the upper number. Diastolic pressure, the force exerted when the heart is at rest, is on the bottom-in more ways than one.

Detailed explanation-4: -Systolic pressure – the upper number in a blood pressure reading – measures how hard the heart pumps blood into arteries. Diastolic – the bottom number – indicates the pressure on the arteries when the heart rests between beats.

Detailed explanation-5: -The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen.
