There are 10 bronchi in each lung.
These are called alveoli. The singular term is alveolus.
The Alveoli are the tiny sacs and they are located through out the whole lung.
Consisting of thousands of tiny air sacs increases the surface area inside of the lung which allows for better gas exchange. If the lung was made of one larger air sac, you would not be able to exchange as many gases (oxygen/CO2) with each breath.
lungs
Each hair follicle contains a tiny lung which allows the cat to breathe directly through the skin.
Normal lung tissue floats because of all the aveoli (tiny air pockets).
They are called Alveoli, look that up on wikipedia, or in your textbook.
The alveoli are the final branchings of the respiratory tree and act as the primary gas exchange units of the lung.
Asbestos, when cut and broken, releases tiny, tiny fibers that float around like dust. When inhaled, they damage the lungs in a way that can develop into cancer.
