What body systems does emphysema affect?
Then, what body systems does COPD affect?
Chronic obstructive pulmonary disease (COPD) affects various structural and functional domains in the lungs. It also has significant extrapulmonary effects, the so-called systemic effects of COPD. Weight loss, nutritional abnormalities, and skeletal muscle dysfunction are well-recognized systemic effects of COPD.
Additionally, what are complications of emphysema? Complications of emphysema can include:
- pneumonia – this is an infection of the alveoli and bronchioles.
- collapsed lung – some lungs develop large air pockets (bullae), which may burst, resulting in lung deflation (also called pneumothorax)
Besides, how does emphysema affect the circulatory system?
Tiny blood vessels absorb oxygen from the air through the walls of the alveoli and deliver it to cells throughout the body. Emphysema destroys the walls between the alveoli. This leaves the lungs less able to absorb oxygen into the bloodstream and remove carbon dioxide from the blood.
What is the pathophysiology of emphysema?
Emphysema is a pathologic diagnosis defined by permanent enlargement of airspaces distal to the terminal bronchioles. This leads to a dramatic decline in the alveolar surface area available for gas exchange. Furthermore, loss of alveoli leads to airflow limitation by 2 mechanisms.
