The alveoli are like plump grapes that are empty inside. They need the plump surface area for capillaries to wrap around them, so Red Blood Cells can trade oxygen molecules for carbon dioxide molecules. But in emphysema, the alveoli collapse. Surface area shrinks. The person cannot get good O2. The body starts to rely on increased CO2 (rather than low O2) to regulate when to breathe.
Emphysema is the breakdown of alveoli.

Emphysema.
Destruction of alveoli reduces the surface area for gas exchange
False, its permanenst enlargment of the alveoli.

Emphysema
This describes a condition called emphysema, a type of chronic obstructive pulmonary disease (COPD). In emphysema, the alveoli become overinflated and the walls between them are damaged, leading to reduced oxygen exchange and shortness of breath. Common causes include smoking, air pollution, and genetics.
There is no cure for emphysema. The alveoli become damaged; they collapse so gas exchange is reduced.
yes and its indicative of emphysema.
They are called alveoli.
yes, yes it is
