Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The relaxation phase is called ventricular diastole, and during this period pressure in the aorta and pulmonary arteries falls to lower values called diastolic pressure.

Detailed explanation-3: -Pulse is the regular, recurrent expansion and contraction of an artery, produced by waves of pressure, caused by the ejection of blood from the left ventricle of the heart as it contracts.
