Nov 19, 2024 · Emphysema is a long-term lung condition that causes shortness of breath. Over time, the condition damages the thin walls of the air sacs in the lungs called alveoli. In healthy lungs, these sacs stretch and fill with air when you breathe in. The elastic sacs help the air leave when you breathe out.

Emphysema causes the small alveoli in your lungs to break and develop into large air pockets. What is emphysema? Emphysema is a lung disease that results from damage to the walls of the alveoli in your lungs. A blockage (obstruction) may develop, which traps air inside your lungs.

Emphysema is a progressive chronic lung condition in which the tiny air sacs (alveoli) are damaged or destroyed. When this happens, it causes the tiny air sacs to rupture and create …

Mar 22, 2025 · Pulmonary emphysema is defined as the "abnormal permanent enlargement of the airspaces distal to the terminal bronchioles accompanied by destruction of the alveolar wall 1. The criteria "absence of obvious fibrosis" may not be necessary because interstitial fibrosis may be present in cigarette smokers' emphysematous lungs 13.

Jan 26, 2023 · Emphysema is a pathological diagnosis affecting the air spaces distal to the terminal bronchiole. It is characterized by abnormal permanent enlargement of lung air spaces with the destruction of their walls without any fibrosis and destruction of lung parenchyma with loss of elasticity.

Mar 24, 2023 · Emphysema is a respiratory disease. In this condition, millions of the lungs' tiny air sacs (alveoli) stretch out of shape or rupture. As these thin, fragile air sacs become damaged or destroyed, the lungs lose their natural elasticity. They become unable to empty easily. Emphysema is a progressive disease, which means it continues to get worse.

Emphysema can result from increased alveolar wall cell death and/or failure of alveolar wall maintenance (1). The literature indicates that chronic inflammation and increased oxidative stress contribute to increased destruction and/or impaired lung maintenance and repair in emphysema.

Emphysema is primarily a pathological diagnosis that affects the air spaces distal to the terminal bronchiole. It is characterized by abnormal permanent enlargement of lung air spaces with the destruction of their walls (septa of alveoli) without any fibrosis and destruction of lung parenchyma with loss of elasticity.

Emphysema is a lower respiratory tract disease, [7] characterised by enlarged air-filled spaces in the lungs, that can vary in size and may be very large. The spaces are caused by the breakdown of the walls of the alveoli, which replace the spongy lung tissue.

Emphysema is a progressive chronic lung condition in which the tiny air sacs (alveoli) are damaged or destroyed. When this happens, it causes the tiny air sacs to rupture and create one big air pocket instead of many tiny ones. Air becomes trapped in the damaged areas and doesn't move the oxygen correctly through the body.
