When ausculting the heart, which valves are heard best on the left side of the chest?

When you're auscultating the heart and you want to osculate on the left side, there are 3 different valves you can hear. 
The first is the Pulmonary valve at the 2nd intercostal space 
the next is the Tricuspid valve at the 4 intercostal space, right by the sternum.
The final is the Mitral valve at the 5th intercostal space, 1cm medially to the midclavicular line.

The fetus at this stage is curled up, almost doubled over, so remember to consider this as you draw the fetus the correct length
