Results In Abnormal Distention And Destruction Of The Alveoli. These abnormal changes contribute to viral propagation and ultimately cell destruction and destruction of infected cells may lead to extensive lung damage. It is the end stage of a process that has progressed slowly for many years.
Emphysema also called pulmonary emphysema condition characterized by widespread destruction of the gas-exchanging tissues of the lungs resulting in abnormally large air spaces. Abnormal distention of air spaces beyond the terminal bronchioles with destruction of the walls of the alveoli Decreased alveolar surface area increases in dead space impaired oxygen diffusion Hypoxemia results. Emphysema is a pathological term that describes an abnormal distention of the air spaces beyond the terminal bronchioles with destruction of the walls of the alveoli.
Lungs affected by emphysema show loss of alveolar walls and destruction of alveolar capillaries.
All these result in the volume and. Results from destruction of the walls of over distended alveoli. Results in the distension and destruction of the whole clusters of alveoli particularly in the lower lobes of. A pathological condition of the lungs marked by an abnormal increase in the size of the air spaces resulting in labored breathing and an increased susceptibility to infection.
