Lungs is made up of
Elastin and collagen fibers
What is the Alveolar pressure in cmH2O
-1cmH2O
What is the pleural pressure in cmH2O
-5cmH2O but can be more negative up to -7.5cmH2O
What is the sum of all partial pressy

Boyle’s Law
Increase pressure= Decrease volume or vice versa
Characterized by airflow obstruction making it difficult to exhale due to narrowing of airways
Obstructive lung disease
Characterized by reduced lung volume, the lungs are restricted to fully expand. There’s a stiffness in the lungs
Restrictive lung disease
Decrease FEV1/FVC (<70%) indicates
Obstructive lung disease
Decrease FVC and Normal/Increased FEV1/FVC ratio (>80%) indicates
Restrictive lung disease
Tidal volume or the amount of air coming in
500 ml
Ability if the lungs to expand
Lung compliance
