Question

what is meant by systole and disystole​

Answer 1

Answer:

systolic mean high pressure, diastolic mean low pressure

Answer 2

Systole -occurs when the ventricular muscles contract ,the cuspid valves close ,the ventricles decrease in size while pressure increases to force blood out of the heart into the arteries.       Diastole- occurs when the ventricular muscles relax ,the volume in each ventricle increases while pressure decreases .This allows blood to flow into the ventricles
