Large surface area due to the combined spherical shape (600 million alveoli = 80 m2)
Flattened epithelial cells of alveoli and close association with capillaries
Short diffusion distance from alveoli to blood (0.5-1.0 um)
Dense capillary network
Moist surface for the solution of gases
they give the lungs a really big surface area
they have moist, thin walls (just one cell thick)
they have a lot of tiny blood vessels called capillaries.
and erm....that's all that i can think of....
large surface area
film of moisture
surrounded by blood capillaries
only one cell apart between the walls of the alveoli and capillary
the alveoli. without the billions of alveoli the lungs could not exchange CO2 for 02
Alveoli alveoli - air sacs in your lungs
The alveoli of the lungs
The actual air exchange takes place in the alveoli of the lungs
The lungs are comprised of alveoli.
alveoli
Alveolar means pertaining the the alveolus (plural alveoli), the small air sacs in the lungs.
The air spaces in the lungs are called pulmonary alveoli. They are where gas exchange occurs in the lungs of mammals.

I Think You Thinking Of The Alveoli/Alveoli's
lungs
Yes, only in the lungs.
