(M) Assume the allergen from Problem 7A.12 causes asthma that constricts the airways by 50%. Assume an allergen is in an aerosol form (1.0 (g/L air)) and can be inspired and expired at same rate as normal air and reaches an equilibrium concentration of allergen in the lungs of 1.0 g/(L air). Write equations describing the loss of allergen from the asthmatic lung, assuming no further exposure.
