emphysema and fick's equation - airway obstruction as a result of inorganic particles --> triggers the production of elastase which breaks down elastin --> alveoli lose elastance --> alveoli recoil --> increase in T and decrease in A --> lower gas exchange inspired partial pressure - Pi,o2 = Fo2 * (Patm - Ph2o) air conditioning during inhalation: adds warmth and moisture to the gas --> water gets evaporated in the mucosa, generating a water pressure which decreases the at...
