Anatomy of the LRT Airway branchings & LMB vs RMB Name levels from trachea to alveoli Changes as we descend resp tract? Pleural cavity Lungs – lobes and fissures Circulation Innervation
Physiology - mechanics Pleural pressure Muscles and movements in inspiration Muscles and movements in expiration Passive vs active expiration Forces keeping alveoli open vs closed
Physiology Ventilation Pulmonary ventilation vs alveolar What causes dead space?
Physiology Diffusion What are the layers of the blood-air-barrier? What effects the rate of diffusion?
Physiology Perfusion Normal V/Q ratio Hypoxic pulmonary vasoconstriction
Pathology of obstruction Tubes – muscular vs non-muscular Non-mechanical Mechanical - extramural, intramural and intraluminal Examples Consequences
