In brief: Very complex

If your heart were one room w/2 doors, completely filled w/ blood, systolic=back door shuts&walls close in, pushing blood out the front door.Diastolic=front door slams behind the blood&back door opens again, filling heart as the walls return to room size.
Your body's vessels is the pipe between both doors.Systolic=pipes stretch&receive blood;diastolic=pipes push back, returning blood to back door.
