There is no set number of valves in your body.
The most obvious number might be FOUR because most people are aware of the four valves in the heart which maintain the correct direction of blood flow from atria to ventricles and then from ventricles to arteries.
The reason there is no single answer to the question is because large veins contain one-way valves that help to return blood to the heart.
In addition, the lymph vessels also contain one-way valves that help to move lymph.
So there is no correct answer. Maybe some medical anatomist can tell us the exact number but I am not sure that anyone knows how many valves are in the veins and lymph vessels.
One valve is the mitral valve in the heart.
