Biology Q: Why is exhalation easier but inhalation more difficult as occurs with pleurisy? (see details)? - more on pleurisy
I want to know why facilitating the accumulation of fluid in the thoracic cavity end, but inhalation is much more difficult? (Note: This happens with pleuritis.)
Thank you for helping us!

Normally, a thin gap is filled with fluid - pleural space - the two layers of the pleural membrane smooth glide over each other. During inspiration expands.When the pressure on the lungs and chest, these layers ignited by excessieve fluid, rubbing painfully with every breath of their rough surfaces, like two pieces of sandpaper. The liquid increases the pressure on the lungs, thereby moving their ability to freely.
During expiration coast relax our muscles. Thus, membranes are not under the crowbar and the liquid fills the empty spaces. Therefore, it is easier than breathing fuild inhalation, if it accumulates in the chest cavity.
