What role do the heart valves have within the function of the heart?

Heart is a pumping muscle responsible for circulating oxygen-rich blood throughout your body. There are four chambers inside the heart: the two upper chambers are called atria and the two lower chambers are called ventricles. The heart muscle squeezes blood from chamber to chamber.
The heart contains four valves, which open to allow blood to move forward through the heart and close to prevent blood from flowing backward.
• The mitral valve allows blood to move from the left atrium into the left ventricle.
• The aortic valve allows blood to move out of the left ventricle.
• The tricuspid valve allows blood to move from the right atrium into the right ventricle.
• The pulmonary valve allows blood to move from the right ventricle to the lungs.
The valves ensure that blood flows in a single pathway through the heart by opening and closing in a particular time sequence during the cardiac cycle. When heart valves become diseased or damaged, they may not fully open or close. This can seriously impair cardiac function by causing blood to leak back into cardiac chambers or by requiring heart chambers to contract more forcefully to move blood across a narrowed valve.

What is the role of papillary muscle?
The papillary muscles are muscles located in the ventricles of the heart. The role of the papillary muscle is to prevent inversion or prolapse or the atrioventricular valves.
What is the difference between a role and a function?

What is the role of the chordea tendineae?
The role of the chordae tendinae (or heart strings) hold the positions of the flaps from the valves (tricuspid and the bicuspid/mitral valve) they basically help with preventing the backward flow of blood. The tendinae are attached to the valves and the papillary muscles :)
What is the role of accounting function within a large organization?

What is the role of the finance function within a large organisation?
The role and the purpose of the accounting function can be identified 'to ensure the business's transactions are recorded and processed completely accurately and securely, and that relevant information is given to management'.
What are artrioventricles?
Atrioventricular valves ar the valves in the heart that lie between the atria and the ventricles. These valves stop the the blood from flowing back (in the wtong direction) from the ventricles into the atria. There are two atrioventricular valves, on the right is the Tricuspis and on the left is the Bicuspid or Mitral valve.
