Our heart is a pump and needs healthy valves to function optimally. There are 4 valves in our heart, two located between the chambers (Mitral and Tricuspid) and the other two located between the chambers and blood vessels (Aortic and Pulmonary Valves). When open, the valves allow the blood to flow only in one direction; when closed, these valves form a strong seal between the different chambers of heart as well as blood vessels.
