Step 1

The heart is the epicenter of the cardiovascular system and is one of the major organs of the body that is essential for vitality and is concerned with the distribution of oxygenated blood to various regions across the body. Due to its iconic and efficient pumping nature, the heart is able to distribute blood to even the narrowest regions of the body that benefit from respiratory gases, nutrients, secondary molecules, hormones along blood. The process of pumping of the heart is carried out with the help of well-maintained and highly specific contraction and relaxation activities that are conducted by the electric conduction system of the heart is known as the cardiac cycle.
