Expert Solution

Step 1 Introduction on Diastolic and systolic phase:

Each cardiac cycle has a diastolic phase where the heart chamber is in a state of relaxation and fills with blood that receives from the veins and a systolic phase where the heart chambers are contracting and pumps the blood towards the periphery via the arteries. Both the atria and the ventricles undergo alternating states of systole and diastole. In other words, when the atria are in diastole, the ventricles are in systole and vice versa.
