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.
one feature is that an alveoli has a wide surface area. If you know any other features then add them!
because it does
the septum
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 is a pale cell that in the septa in lungs between pulmanory alveoli which keep alveoli away from collaposing
It allows for rapid diffusion of gasses.
alveoli
gas exchange is the intake of the oxygen and the let out of the carbon dioxide
They have capillaries close to their surfaces.
