the aveoli
The alveoli in the lungs.

Alveolar sac and alveoli
Respiratory surface is the surface where respiratory gas exchange in an animal. Ex-lungs
They are called alvioli (al-vee-oh-li)
Respiratory surface is the region where gaseous exchange occur. It includes respiratory bronchiole, alveolar duct and alveolus. Large surface surface is needed the increase the diffusion rate of gaseous. Respiratory surface also exhibit other properties such as moist and only one-cell thick. Nika G.
Ozone can affect both lungs and respiratory system. It is because it acts as a pollutant over the surface.
I think you mean the diaphragm, and that's part of the respiratory system. It's a muscle below the lungs, and when it tightens, it increases the volume of the cavity the lungs are in, so the lungs increase in volume as well, and air rushes into the lungs.

Black Lung disease works by building up coal dust on the surface area of your lungs, therefore reducing the overall surface area of your lungs and reducing the efficency of the lungs.
Microvilli are tiny, finger-like projections found on the surface of cells in the respiratory tract, particularly in the lungs. They primarily function to increase the surface area for absorption of nutrients and gases. However, microvilli do not play a direct role in cleaning tar out of the lungs. The clearance of foreign particles like tar is primarily carried out by the mucociliary escalator, a system in which mucus traps particles and cilia move the mucus out of the respiratory tract.
