I'm wondering why it's present only in right ventricle, and not in the left ventricle.

Thanks a million!

Moving to the top.

It carries the impulse from the right bundle branch --> right ventricular wall, which in turns allow more coordinated contraction of the heart

The thickness of the left ventricular wall enables the purkinje fibers of the left bundle to be embedded in the wall. The right side is thinner and therefore needs an extra bit of "meat" for the bundle to travel in.
