Question
Differentiate between the following:
Systole and Diastole

Answer

SYSTOLEDIASTOLE
This is the phase during which the heart contracts.This is the phase of rest or relaxation of the heart muscles.
During systole, the atria send blood into the
ventricles to be ejected from the ventricles to the
corresponding vessels.
During diastole, the heart chambers fill with blood and the supply of the cardiac muscle is improved.
Time taken for atrial systole is 0.1 to 0.16 seconds
and ventricular systole is 0.3 seconds.
Atrial diastole lasts 0.7 to 0.76 seconds and
ventricular diastole lasts 0.5 to 0.56 seconds.
