Pulmonology ยท Lung development stages, surfactant biology, congenital malformations, tracheobronchial anatomy, respiratory epithelium, pulmonary vasculature, and defense mechanisms
By completing this question set, you will be able to trace lung development through five stages and predict the consequences of premature birth at each stage. You will describe surfactant composition, production, and function, apply LaPlace's law to explain alveolar stability, predict NRDS from risk factors, and trace the pathophysiology from surfactant deficiency through atelectasis to respiratory failure. You will identify congenital lung malformations and predict their clinical presentation from the developmental defect. You will apply tracheobronchial anatomy to predict foreign body aspiration patterns. You will correlate respiratory epithelial cell types with their functions and predict disease consequences of cellular dysfunction. You will describe the dual pulmonary blood supply, explain hypoxic pulmonary vasoconstriction, and identify the pulmonary defense mechanisms whose failure predisposes to pneumonia.
