Expert Solution

Step 1- Introduction

ATRIAL FILLING:-

During the cardiac cycle, there is an alternating sequence of contractions and relaxation to pump blood and distribute throughout the body.

Both ventricles and auricles or atria will have alternating phases of systole and diastole.

Out of the total filling phase, the atrial filling is only approx 10% of all ventricular filling because the transport of blood from the pulmonary vein occurs in the left atrium and then to the left ventricle and the filling of ventricles occurs early to atrial filling.
