the pleural membrane covers both the inside of the chest wall and the outside of the lung on each side of the chest;
Each pleural membrane is several cells in thickness;
Each pleural membrane is an epithelial tissue
The pleural cavity contains a small amount of serous (watery) fluid.
Cellular respiration;
breathing movements
diffusion across membranes
Active transport of gases
the process of moving air into and out of the lungs;
The process of gas exchange between blood and air;
The process of moving air into and out of the upper part of the respiratory tract;
The process of gas exchange between blood in the systemic capillaries and tissue fluid.
it separates the abdominal and pelvic cavities;
It has both fibrous and muscular parts;
It is not involved in forced expiration
It is a perfectly flat structure

It is normally an active process;
At rest, it typically relies only on the elastic recoil of the lungs;
In forced expiration, the internal intercostal muscles may be used;
it aims to generate a pressure gradient to the external atmosphere from the interior of the chest cavity;
