The surface area of the alveoli is where oxygen and carbon dioxide are exchanged across membranes. A large surface area enables a greater amount of gas transfer. The skin has two main functions: one is holding all our bits in one place and the other is to maintain body temerature. In the latter role, a large surface area is good for cooling the body but bad for keeping warm. So it is a compromise.

The pleura is a membrane that surrounds the lungs of mammals. Presumably, the phrase means that the surface of the pleura was found to be normal in an examination.
The skin surface is not large enough for big creatures such as humans; therefore we have structures in our lungs that greatly increase the surface area.
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
Your lungs have very large surface area. About 100 square meters or 1100 square feet.
There are about 300 million of them, covering a total area of 70 to 90 square meters of surface within the lungs. There are plenty of them to share the work and to share and spread the pulmonary pressures involved.
Lungs alveoli has very large surface area, about 100 square meters. So air is fully saturated with water vapor and so it is more in amount.
The alveoli in the lungs.
alveoli
I believe its the alveoli in the lungs. These alveoli provide a large surface area for gaseous exchange.
Alveoli in the lungs provide the greatest surface area for gas exchange in the body. They are tiny air sacs that are surrounded by capillaries where oxygen and carbon dioxide are exchanged during respiration. The numerous alveoli increase the total surface area available for this gas exchange process.

In an average adult with healthy lungs we find approximately 300 million alveoli with a total surface area approaching 150 meters square, or the size of a tennis court.70m2The edzact size of a tennis court xxxTypically between 50 and 100 square meters160 meters squared.
Alveolar sac and alveoli
Alveoli are found within the lungs. The alveoli act as a specialised gaseous exchange surface in mammals. Another function of alveoli is the production of surfactant.
the coughing causes the walls of some of the alveoli in the lungs to burst. when this happens the surface area of the lungs in contact with the air is reduced.
