Answer:
The valves present in the heart normally allow the blood to flow in only one direction. There are four valves in the heart – mitral valve, tricuspid valve, bicuspid valve and pulmonary valve. These valves control the flow of blood by opening and closing through the heart at the time of contraction.Sep 19, 2013
