See the lab Activity Sheet for potential extensions of the concept to structures of alveoli
dilate and the walls dissolve
One possible explanation for this is that the IPAP has ventilated the alveoli
still expanded by air and removed the nitrogen, having replaced the alveolar air with oxygen, so the capillaries can now absorb the alveolar gas and completely collapse the alveoli
You are probably growing new alveoli
up until age 8 or maybe even later, and so it may be that having this chronic irritation in the lungs would interfere with that process," said Dr.
The gonads contain abundant alveoli
with reduced interalveolar space.
When underlying parenchymal disease is present, the alveoli
may be weakened; as a consequence, alveolar rupture can be caused by changes in pressure that are less dramatic.
Air still travels through your nose, down the trachea, and finally to the alveoli
where oxygen enters your blood and CO2 is sent back into the air .
researchers reported that female mice deprived of estrogen by having their ovaries removed lost 45 percent of their working alveoli
, the tiny sacs in the lungs that deliver oxygen to the bloodstream and remove carbon dioxide from it.
Finally, these tiny tubes end in balloon-like air sacs called alveoli

Other potential mechanisms include bronchopleural fistula, rupture of dilated alveoli
distal to a stenosis, chemotherapy-induced impairment of repair processes, and persistent local infection.
Nascent leaves, the alveoli
of Mother Earth's lungs, shimmer like pale emeralds in the bright sun, impatient to begin the process that sustains life.
