systole and diastole

Systole and Diastole

When blood is filled from atria into ventricles, ventricles are relax at that time and that period is called " Diastole"

When the blood from the ventricles is pushed into the lungs and systemic circulation, ventricles are contracted , that period is called "Systole".

Systole is equal to " ventricle contraction,"

Diastole is equal to "ventricle relaxation"

Blood pressure = 120/80 mmHg Systole/ Diastole.  VentRicle contraction/ Ventricle relaxation
