Our lung is not a single entity .The right lung is divided in three segments & left lung is divided in two segments.Each part does have its own blood supply & draining channel which summits in main artery & nerves.
In the initial stages the effusion does try to rest in lower part due to effect of gravity but it is not nesecessary.With spread of disease it does spread in whole lung.

Hope this will help you.
