Respected sir/mam,

I want to know how many valves are present in the heart, which are those(names) and where they present.

In order of blood circulation, there are four valves present in the human heart- tricuspid valve, pulmonary valve, mitral valve and aortic valve. 
The mitral valve and tricuspid valve, which controls blood flow from the atria to the ventricles.The aortic valve and pulmonary valve, which controls blood flow out of the ventricles
