It is implicated as responsible for the heat resistance of the endospore.

These cells cause disruption of the normal air spaces (alveoli) where oxygen is extracted from the atmosphere.

In the gas phase, it can be used to image empty space such as cavities in a porous sample or alveoli in lungs.

Once in the lungs, bacteria may invade the spaces between cells and between alveoli, where the macrophages and neutrophils (defensive white blood cells) attempt to inactivate the bacteria.

Macrovesicular is the more common form of fatty degeneration, and may be caused by oversupply of lipids due to obesity, obstructive sleep apnea (OSA), insulin resistance, or alcoholism.

The infection of herbivores (and occasionally humans) by the inhalational route normally proceeds as follows Once the spores are inhaled, they are transported through the air passages into the tiny air sacs (alveoli) in the lungs.

Breathing 100 oxygen also eventually leads to collapse of the alveoli (atelectasis), while at the same partial pressure of oxygen the presence of significant partial pressures of inert gases, typically nitrogen, will prevent this effect.
