Explanation:
Detailed explanation-1: -The opening and closing involve a set of flaps called cusps or leaflets. The cusps open to allow blood to flow out of a chamber and close to allow the chamber to refill with blood. Heart valve diseases can cause backflow or slow the flow of blood through the heart.
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.
