Emphysema

Emphysema Lung disease where the alveoli -parts of the lungs where gas is exchanged- have lost their elasticity. Breathing becomes increasingly difficult, and emphysema patients have to use other muscles to breathe out. The main cause of emphysema is smoking.
RELATED TERMS--------------------------------------
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Alveoli
The sacs in the lungs at the ends of the smallest airways where oxygen is exchanged for carbon dioxide in the blood.
Lungs
The main respiratory organs in the chest where blood is oxygenated.
Breathing
The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction, and then exhaled due to muscle relaxation.
