There isn't any: in practice, although there are in theory. PURE emphysema involves only the small air sacs, which become less capable of diffusing oxygen into the bloodstream and clearing carbon dioxide, enlarge and coalesce with othrs. Pure bronchitis inflames and narrows the smaller air passages so that oxygen/CO2 can't get through. Most patients have BOTH of these processes, though one may predominate.Both bad
