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.
There are multiple reasons. First alveoli are coated with a substance known as "surfactant" to prevent them from collapsing. Second, there is a medium for immunoglobulins such as IgA to exist so that pathogens in the air can be defended against. Third, the air that enters the lungs is humidified to prevent drying and abrasion tissues.
The Alveoli has a moist lining, Because the gases must be dissolved in water in order to get through the walls.
Yes, all gas-exchange surfaces must be wet for efficient transfer of gases.
why do organisms need a moist surface area
Because the gases (CO2 and O2) can only diffuse in solution
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!
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.
because it does
alveoli
It allows for rapid diffusion of gasses.
gas exchange is the intake of the oxygen and the let out of the carbon dioxide
They have capillaries close to their surfaces.
keeps them moist
its soft and moist and its ALWAYS helpful
One of the major hormones of pregnancy, estrogen helps maintain the endometrial lining of the uterus. Additionally, progesterone will also help to maintain the uterine lining.
