Pleura is a double layered membrane surrounding each lung.
Pleura is a double layered membrane surrounding each lung.
They are present in the lung surrounding the alveoli.
You have the potential space between the parietal and visceral (outer and inner) pleura. If air happens to enter this space, the lung will collapse to small ball. The space becomes large at once. You have negative pressure in this space.
There are about 30,000 of them in each lung.
There are 10 bronchi in each lung.
First it's larger, second the left lung is sharing space with your heart..

The mediastinum
The left lung has 2 lobes due to the space occupied by the heart, which pushes against the left lung. The right lung has 3 lobes because it has more space in the chest cavity to accommodate the extra lobe.
