A person suffering from mild emphysema stopped smoking cigarettes.

goblet cells secrete more mucus, allowing a greater number of pathogens to be trapped
2 )
increased numbers of phagocytic macrophages arrive in the lungs
3 )
less atheroma build-up on the inner lining of arteries, increasing lumen diameter
less carboxyhaemoglobin produced, increasing oxygen transport by haemoglobin
