what is the difference between systolic and diastolic?

Answer 1

Systolic is the measurement of pressure put on the vasculature while the heart is pushing blood. Diastolic is the measurement of pressure put on the vasculature while the heart is at rest.

Answer 2

Two numbers are used to describe blood pressure:

* Systolic. The systolic pressure (the higher and first number) measures the force that blood exerts on the artery walls as the heart contracts to pump out the blood.

* Diastolic. The diastolic pressure (the lower and second number) is the measurement of force as the heart relaxes to allow the blood to flow into the heart.

Answer 3

Systolic and diastolic blood pressure


Systolic blood pressure refers to the pressure of blood in the artery when the heart contracts. It is the top (and higher) number in a blood pressure reading.

Diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats. It is the bottom (and lower) number in a blood pressure reading.

For example, if a person's systolic pressure is 120 millimeters of mercury (mm Hg) and the diastolic pressure is 80 mm Hg, blood pressure is recorded as 120/80 and read as "120 over 80."

Answer 4

its exactly the opposite. both greek words, systolic means something that shrinks, that becomes smaller, diastolic means something that gets larger. that is the meaning of the actual words, the girl above describes the medical terms which are correct. dont know which explanation you want!

Answer 5

systolic: blood pressure when heart muscles contract
diastolic: blood pressure when heart muscles relax

Answer 6

If you mean what's the IDEAL difference then the answer is A.
