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 ...

Healthy lung tissue contains many air-filled alveoli, in which oxygen is absorbed from the respiratory air into the blood (left). In fibrotic lung tissue, these have been displaced by connective ...

This cancer originates in the epithelial cells that line the lung’s alveoli, the tiny sacs responsible ... prepared samples of lung tissue, in which epithelial cells are a minority — Kadara ...

Smoking damages the alveoli, causing lung tissue to become inflamed and scarred. Scarred tissue is thicker and less flexible, so the lungs can’t fully expand, which lowers the amount of oxygen ...

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 ...

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 ...

When these tissues are damaged, you cannot inhale as deeply as you should. Rales can change as the underlying condition gets worse. Fine crackles are generally heard when the alveoli are affected ...

small size - each of the alveoli is a small sphere about 300 μm in diameter, giving it a larger surface area to volume ratio than larger structures number - there are around 700 million alveoli ...

Common symptoms of ILD include: The interstitium is a thin layer of connective tissue that supports your lungs' alveoli (air ...

Proliferative bronchiolitis with intraluminal polyps may be limited to the bronchioles, but often extends into respiratory bronchioles and alveoli with intra-alveolar buds of granulation tissue ...
