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. It starts at the beginning of one heartbeat and ends at the beginning of another.
Detailed explanation-2: -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.
Detailed explanation-3: -The pressure of blood inside the artery during ventricular relaxation is called systolic pressure.
