The porous membrane contains cavities or alveoli which are assumed to shaped by enzymatic activity by exosomes (One-exosome-like body is shown in higher magnification in the inset). Authors ...

When silica dust enters the lungs it can cause swelling and gradually leads to areas of hardened and scarred lung tissue (fibrosis) Silica dust becomes trapped inside the alveoli, the tiny air ...

The alveoli are adapted to provide a very large surface area for gaseous exchange: small size - each of the alveoli is a small sphere about 300 μm in diameter, giving it a larger surface area to ...

Most of them also apply to other exchange surfaces such as the small intestine, body tissues and placenta. Thin lining: the lining of the alveoli is very thin so that gases can quickly diffuse ...

There are over 200 types of interstitial lung disease (ILD). While ILDs are a diverse group of lung diseases, they all affect the interstitial space (interstitium)—a network of blood vessels and ...
