The wall is thin to allow rapid andefficient diffusion across of O2 into the blood and CO2 into the alveolar space (the air). It is moist for many reasons but primarily because diffusion in this form must be in slution.
Surfactants, which are molecules that lower surface tension, can be found in serous fluid. These molecules help prevent alveoli in the lungs from collapsing by reducing the surface tension of the fluid lining the alveoli.
The alveoli is the point where the waste product of respiration (carbon dioxide) and oxygen are diffused into or out of the blood. Oxygen diffuses into the blood stream and are carried to the heart and carbon dioxide is diffused out of the lungs and expired. The alveoli have moist walls and are close to the capillaries which speeds up the process.
No gingir ale does not help. What can help is nice moist soil and a good amount of sun.
the septum
one feature is that an alveoli has a wide surface area. If you know any other features then add them!
O2 and CO2 are carried by the blood. Gases moves by diffusion that is, they move from an area of higher concentration to an area of lower concentration. The lining of the alveoli most be moist to help gases diffuse.

It allows for rapid diffusion of gasses.
gas exchange is the intake of the oxygen and the let out of the carbon dioxide
The alveoli have several key characteristics that facilitate the easy diffusion of oxygen into the blood capillaries. They possess a large surface area due to their numerous tiny sacs, which increases the area available for gas exchange. Additionally, the alveolar walls are extremely thin (only one cell layer thick), minimizing the distance oxygen must travel to reach the capillaries. Finally, the moist environment within the alveoli helps dissolve oxygen, further aiding its diffusion into the bloodstream.
