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.

∙ 14y agoThere 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.

How do alveoli and capillaries help to get oxygen?
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.
Do plants grow with ginger ale?
No gingir ale does not help. What can help is nice moist soil and a good amount of sun.
How does the structure of the alveoli help do it jobs?
one feature is that an alveoli has a wide surface area. If you know any other features then add them!
What three important physical features does the gas exchange membrane in the lungs need to have to be efficient?
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.
How does 300 million alveoli help gaseous exchange?
because it does
What are the structures you find inside the lungs that help us breathe?
alveoli
How thin walls help the alveoli?
It allows for rapid diffusion of gasses.
What are the characteristics of the alveoli that help with its function?
gas exchange is the intake of the oxygen and the let out of the carbon dioxide
How does alveoli help two gases diffuse quickly into and out of the blood?
They have capillaries close to their surfaces.
How does the humus layer help plants grow?
keeps them moist
How does a peach help with your health?
its soft and moist and its ALWAYS helpful
How is the uterine lining maintained during pregnancy?
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.
