Explanation:
Detailed explanation-1: -Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle . Vibrations of these structures from the blood flow create audible sounds-the more turbulent the blood flow, the more vibrations that get created.
Detailed explanation-2: -As your heart pumps blood, four valves open and close to make sure blood flows in the correct direction. As they open and close, they make two sounds that create the sound of a heartbeat. The four valves are the aortic valve, mitral valve, pulmonary valve and tricuspid valve.
