Review lung compliance and airway resistance under normal and pathophysiological

Question

Review lung compliance and airway resistance under normal and pathophysiological conditions by placing the correct term into each blank. Thickening of the lung tissues, as occurs with the disease cystic fibrosis , decreases lung compliance. Increased concentration of alveolar cells increases lung compliance. secreted by type II increases within the fluid layer lining the alveoli decreases Surface tension ung compliance is characterized by the destruction of the alveolar walls leading to increases in compliance. Emphysema Decreased diameter of bronchioles due to airway inflammation, as occurs during a(n) , decreases air flow. asthma attack Increased resistance of bronchioles due to excessive mucus production from chronic bronchitis air flow. decreases Bronchodilationair surfactant

Explanation / Answer

thickening of the lung tissue has occurred with the disease cystic fibrosis

Increased concentration of surfactant secreted by type 2 Alveolar Cell increased lung compliance that absorb Na and H2O preventing fluid build up within the alveoli.

Surface tension with in the fluid layer lining the alveoli decreases lung compliance.

Emphysema is characterized by destruction of alveolar walls,

Decreased diameter...........asthma attack...... in

Increased resistance to bronchioles due to excessive mucus production from chronic bronchitis decreas air flow

Brochidilation increase blood flow
