Two sets of valves primarily supervise your coronary heart's blood move. The atrioventricular valves sit between the atrium and ventricle. On the left side of your coronary heart, this specific gateway is named the mitral valve, and on the precise, the tricuspid valve. The semilunar valves, nevertheless, serve as the exit doors that blood pulses by means of because it leaves the ventricles on its method to the gas traces (your arteries).
