Weibel Model Of Airways
Pressures In Lung During Inspiration/Expiration
Gas Exchange at the Alveolus
Alveolar Cells
Pulmonary Surfactant
Surfactant in Lung decreases Surface Tension
Surfactant Reduces Surface Tension Preventing Collapsse Of Alveoli
Without Surfactant = Increased Surface Tension
Increased Surface Tension = Alveolar Collapse
Collapse Of Alveoli = Exchange Of Gases Become Difficult
Surfactant Dysfunction = Increased Inflammation/Host defense Impaired
Current Events
COVID 19 reduces Surafctant
