Explanation:
Detailed explanation-1: -The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body.
Detailed explanation-2: -During this cycle, the period of relaxation is called diastole and the period of contraction is called systole. In this article, we will explain how diastole and systole relate to blood pressure.
Detailed explanation-3: -There are 2 phases to your heart’s pumping cycle: systole – this is when your heart contracts, pushing blood out of the chambers. diastole – this is the period between contractions when the muscle of your heart (myocardium) relaxes and the chambers fill with blood.
