Pleura

Vita capacity
Measure votal capacity
SPIROMETER
Irritation of respiratory pathways
Bronchial swelling and blockage; wheezing, short breath, coughing
Respiratory pathways become infected
Bronchitis
Alveoli destroyed;
Emphysema
Results to reduced surface area for gas exchange, extreme difficulty breathing; often fatal
Emphysema
Lung infection causes the alveoli to collect mucous material.
Pneumonia
Bacterial lung infection
- Destroys lung tissue
- Decrease in effective gas exchange.
Pulmonary Tuberculosis
genetic defect; lungs filled with thick, gummy substances
Cystic Fibrosis
uncontrollable growth of abnormal lung cells
Lung cancer
