Why are human lungs lobed asymetrically? Two lungs share a total of five lobes-why?

What functionality do these sub-divisions provide in respiration?

The asymmetry is due to the necessity of fitting in the heart and mediastinal structures.

There is no difference in lobe function except for the pressure differentials exhibited with more air distributing to the lobes that are lowest.
